Mechanics advantage of joint position
WebDec 1, 2004 · Muscular forces generated during locomotion depend on an animal's speed, gait, and size and underlie the energy demand to power locomotion. Changes in limb posture affect muscle forces by altering the mechanical advantage of the ground reaction force (R) and therefore the effective mechanical advantage (EMA = r/R, where r is the muscle … WebThe ratio of the output force to the input force is known as the mechanical advantage of the linkage, while the ratio of the input speed to the output speed is known as the speed ratio. …

To multiply a hand force at the handle into a high clamping force to hold work. 2.) To create an over-center lock to prevent the clamp from opening and releasing the work until opened by the operator. 3.) To rapidly open and close the clamp giving a wide clearance in which to load and unload the workpiece.
WebThe linkage is dimensioned so that the linkage reaches a toggle position just before it folds. The high mechanical advantage allows the input crank to deform the linkage just enough to push it beyond the toggle position. This locks the input in place. Toggle mechanisms are used as clamps.
