In the previous analysis it was assumed that the bar was inelastic. In practice the 28 mm diameter steel bars used by gymnasts deform by around 0.1 m at the lowest point of a giant circle. Suppose that the bar deforms by a distance h during the downswing (figure 3). If the initial angular velocity is zero at the highest point the.

. potential energy is converted to kinetic energy when the mass moves downward. The velocity must increase as the mass moves downward from the top of the circle, subject to the constraints stated. For a mass moving in a vertical circle of radius r = m, if we presume that the string stays taut, then the minimum speed for the.

is attached to the end of a light inextensible string whose other end is attached to a rigid beam. Suppose, further, that the object is given an initial horizontal velocity such that it executes a horizontal circular orbit of radius $r$ with angular velocity $omega$. See Fig. 60. Let $h$ be the vertical distance between the beam and.

I probably would have calculated the angular velocity at the top of the circle. But the question is clearly ambiguous, and I don't think it was unreasonable of you to take "the angular velocity of. the swing" to mean the initial velocity of the swing, starting from the bottom. The question should have said.

Jul 16, 2015. Hi, I was trying to get an object to rotate in a random direction very very slowly. But I found that there seems to be a limit to how slow it can rotate because when i tried to get it to rotate at less than.02 units it seems to start rotating and stops. I have no angular drag on my rigidbody or gravity. This is my code:.
