The links have bushings or ball socket type joints to allow more flex and controlled movement. When your vehicle begins to turn, the suspension component at the outside of the turn gets pushed downward. The link attached to the stabilizer bar also gets pushed downward, and applies torsion, or a twisting motion, to the "U" shaped rod.

The rod thus becomes positively charged. Touching the positively-charged rod to two pith ball gives the balls each a small positive charge. Since like charges repel, the pith balls repel one another. If an ebonite rod is rubbed with fur, the rod rubs some electrons off the fur.

interaction between the shape of the ball and the angle between the two rods forms an extra slope, which, combined with the apparent, visible slope of the rods, create a virtual slope for the ball. The ball moves down the virtual slope, which, depending on ball location and rod separation, may be in the opposite direction from the visible slope.

Example 10.11 Rotating Rod Revisited A uniform rod of length L and mass M is free to rotate on a frictionless pin passing through one end. The rod is released from rest in the horizontal position. (A) What is its angular speed when the rod reaches its lowest position? (B) Determine the tangential speed of the center of mass and the tangential

Rotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics. Indeed, the rotational inertia of an object ...

If a plastic rod rubbed with fur is made to touch two small pith balls (now-a-days we can use polystyrene balls) suspended by silk or nylon thread, then the balls repel each other [Fig. 1.1(d)] and are also repelled by the rod. A similar effect is found if the pith balls are touched with a glass rod rubbed with silk [Fig. 1.1(e)].
