Typically, struts consists of a coil spring to support the vehicle's weight, a strut housing to provide rigid structural support for the assembly, and a damping unit within the strut housing to control spring and suspension movement. The bottom of the strut body attaches to the steering knuckle, which in turn connects to a lower control arm through a lower ball joint.
When performing a vertical jump, the athlete exerts force at the low back, hip, knee, and ankle joints. The spine flexes as the athlete squats downwards, and then is extended by the spinal erectors over the course of the jump. The hip extensors (gluteus maximus, hamstrings, and adductor magnus) work to move the trunk and the thigh apart, which pushes the torso up and backwards. Meanwhile, the knee extensors (quadriceps) contract to extend the knee, and the calf muscles contract to move the shin backwards, towards the vertical.
I am in grade 10, 15 years old and 6'1 3/4". I have big hands and can palm the ball...I could touch rim in grade 8 and getting closer to dunking everyday now..it literally takes no effort to touch rim now but whenever I go for the dunk I get the ball above rim easily but have trouble getting that wrist motion to actually throw the ball in the hoop...and help?
I think one way of thinking about it is, less parts of the body, and more the kind of muscle. You want to develop your quick-twitch, or fast-twitch, muscles, because at the end of the day, trying to dunk a basketball is an explosive activity. You’re not going for a long-distance run here. You’re doing three quick steps, a hard shove against the ground, and exploding upwards. So the question is how to turn yourself into basically a sprinter. You do a lot of jumping exercises where you’re doing box jumps, where you jump off one box and as soon as you hit the ground, you try to jump up onto another box. That sort of thing.
slang To best someone in a spectacular fashion and/or in a way that is humiliating to them. In basketball, to "dunk on" a defender is to perform a slam dunk over them, a move often considered humiliating to the defender. The phrase is commonly used in a passive construction ("(one) got dunked on"). Here's the part of the debate where she really dunks on him by completely destroying his argument. You can't just tweet at this person and make fun of their opinion. If you really want to dunk on them, you have to correct their horrible grammar too.

If you can jump high enough to dunk, but you’re having a hard time going up with the basketball in one hand, the solution is to start small and work your way up. A smaller ball such as a soft golf ball or tennis ball is a great starting point. From there, move slowly to a mini-basketball. It will provide more of a challenge but still be easy to palm as you go up. Once you can dunk the mini ball, try moving on to a volleyball until finally a regulation basketball.

During the 2009 NBA dunk contest, Howard had a separate goal brought onto the court, and the rim was noticeably significantly higher than a standard goal. Howard, after going into a 1950s-era telephone booth and again fashioning the Superman attire, caught a pass from Nelson and easily completed a two-handed dunk on the higher goal. While this was not performed for record-setting purposes, the dunk received a perfect score and a warm response from the crowd, in part because of its theatrics. Also in this contest, 5'9" guard Nate Robinson wore a green New York Knicks jersey and green sneakers to represent Kryptonite, playing on Howard's Superman theme. He used a green "Kryptonite" ball, and jumped over the 6'11" Howard prior to dunking. This dunk and the theatrics could have won the competition for Robinson, who was voted the winner by the NBA fans. Robinson then thanked Howard for graciously allowing him to dunk over him, asking the crowd to also give Howard a round of applause.
March 27 was yet another in a long string of days, each feeling as if it would be the day. Fully rested and caffeinated, I arrived with Jeff at a court, recommended by Brent Barry, whose rim heights fluctuated but which I’d recently measured at 10 feet. The rims at New York City’s famed Rucker Park, incidentally, both measured under 9’ 9” on a recent visit, which raises all sorts of questions about what a dunk is and what it isn’t. The famed outdoor rims along Venice Beach, if lined up next to each other, would look like a graphic equalizer during a Ray Manzarek keyboard solo: 9' 9", 9' 11", 9' 8".
Early in my mission, my editor had given me a book, Jump Attack, by Tim Grover, personal trainer to Jordan, Dwyane Wade and myriad other NBA stars. I’d ignored it at first; I figured I knew plenty about how to jump higher. When I finally opened it last December, I was further dissuaded. The exercises Grover prescribed to increase one’s vertical leap looked either nonsensical (hold a deep lunge for 90 excruciating seconds, without moving) or sadistic (the series of rapid-fire bursts and landings that he’d named “attack depth jumps”). These self-immolations, Grover wrote, would last for three months.
En “Diario de mi mente”, Ursula Meier dirige a Fanny Ardant y a Kacey Mottet Klein en la historia de un parricida que le confiesa a su profesora de literatura los motivos que le han llevado a matar a sus padres. En “Sirius”, ambientada en la Masacre del Orden del Templo Solar, Frédéric Mermoud fija su calmada mirada en el adoctrinamiento y el fatal desenlace de los miembros de una secta. En “Nombre: Mathieu”, Lionel Baier representa la capacidad de resiliencia de un joven, víctima de un criminal en los años 80. Finalmente, “El valle”, de Jean-Stéphane Bron, es la realística dramatización de la persecución de un coche en el que viaja un joven ladrón que intenta cruzar la frontera franco-suiza.
About 100 yards away from this 9' 10" breakaway rim (which came to sound, each time I grabbed and released it, like someone closing the metal baby gate at the top of our stairs) was a brown, oxidized, immobile 9' 1" version, a hand-ruining iron maiden where, in front of the occasional puzzled onlooker, I practiced (and practiced) the timing and the hand and wrist work required to dunk. I knew early on that my regulation dunk, if it ever came to pass, would have to come from a lob of some sort—a bounce to myself, either off the blacktop or underhanded off the backboard—after which I would hypothetically control the ball with one hand just long enough to flush it. Mastering the placement and the delicate timing of such lobs would prove to be a quixotic pursuit in and of itself. But it was necessary, not just because of my hand size (7 ¾ inches) but also because I needed to keep my arms free so I could swing them at takeoff, adding much-needed lift to my leap.

Start on a lower hoop and practice on that, just to get the feel of dunking. Jump height is one thing, but you would be surprised at the number of people that find it hard just to slam the ball into the basket, even if they are high enough. Make sure the hoop is high enough for you to only touch the rim. Different jumping styles and distances from the basket can change your vertical drastically and could be the difference between a rim-block and a slam. Keep progressing and eventually you will see results. Good luck!
Thank you very much for your sharing this information. I am excited to start working on your recommendations immediately. The information seems very clear and easy to follow. I like the available links, and the fact that I can use this product on my Kindle, although I am used my PC to view. The book is brief and not full of wordy marketing fluffy verbiage.
Secondly, in addition to the rate of force development, the size of the force itself produces a negative feedback effect on vertical impulse, because higher forces lead to faster accelerations, which in turn reduce the time spent producing force before take-off. This is *partly* why drop jumps tend to involve higher forces, shorter ground contact times, and yet similar jump heights to countermovement jumps.
Whether the result of a 180° spin or body angle at takeoff, the double clutch is generally performed with the player's back toward the rim. While this orientation is rather conducive to the double clutch motion, Spud Webb was known to perform the dunk while facing the basket. Additionally, Kenny "Sky" Walker, Tracy McGrady—in the 1989 and 2000 NBA Contests, respectively—and others, have performed 360° variation of the double clutch (McGrady completed a lob self-pass before the dunk). Circa 2007, independent slam dunker T-Dub performed the double clutch with a 540° spin which he concluded by hanging on the rim.[9]
I mean, I think you can probably improve your vertical some in a month. I think, though, that for most normal people who aren’t teenagers who are trying out for their basketball team, who don’t have all that time on their hands, I think there’s a much saner way to go about it, where you’re steadily improving your vertical over a period of time. You know, there’s a lot of this kind of slightly crazy, kamikaze, self-improvement type of thing, whether it’s trying to jump higher or do anything else. I’m sure those things work to some extent, but it’s not the way I would have wanted to go about it.

The days and jumps and deadlifts and calf raises rolled on, rep by rep, protein shake by protein shake. Six months became seven, then eight. To protect my right hand, I began wearing a canvas gardening glove with the fingers cut off. It soon became stained with blood—the equivalent of Curt Schilling’s bloody sock, but with one-millionth the significance. The rims where I toiled belonged to me now, such that I barely noticed the toddlers wobbling nearby, the skateboarders swirling around me as day turned to dusk, the elderly couple ambling arm in arm, looking for all the world like my wife helping me to the shower on the morning after a double day.
This phase begins with the athlete at the bottom of the jump, just as he begins exploding upwards towards the takeoff. The force-time graph shows that the athlete reaches peak forces shortly after reaching the lowest point of the jump. He then further accelerates until his feet leave the ground and there are no more ground reaction forces measurable.

The vertical jump is defined as the highest point that the athlete can touch from a standing jump, less the height that the athlete can touch from a standing position. The measurement of the jump is flawed if the athlete is permitted to take one or more steps before jumping, as the athlete will convert some of the energy developed in the step taken into the force of propulsion that generates upward lift. Basketball has numerous legends and other urban myths concerning the seemingly superhuman leaping ability attributed to certain players; one such player, former University of Louisville star Darrell "Dr. Dunkenstein" Griffith, was reputed to possess a 42 in (1 m) vertical leap. It is likely that the average National Basketball Association player 6 ft 6 in (1.97 m) or shorter has a vertical leap of between 25 and 30 in (0.63 and 0.75 m); taller and heavier players will usually not be able to jump as high.
