Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.

Equilibrium of Forces

The tension created on one body during push or pull is known as force.

Question

Ant-Man is walking around on top of a wooden plank that rests atop two thin, vertical steel pillars, which are bolted into the ground. Ant-Man’s mass is \( m_1 = 80.0 \, \text{kg} \), but he is small enough to be treated as a point particle. The plank (\( m_2 = 11.7 \, \text{kg} \)) has a length of \( L = 2.44 \, \text{m} \), with the left end flush against the edge of the left pillar. The separation distance between the pillars is \( d = 1.50 \, \text{m} \).

![An image shows a wooden plank on two steel pillars](wooden_plank_on_pillars)

Suppose that Ant-Man walks far enough out from the right pillar so that the plank is just about to start rotating. What will be the magnitude of the force from each of the pillars on the plank at this time? (Hint: begin your analysis by thinking about the torques acting on the plank, and note that the forces from the two pillars are not the same.)

How far out from the right pillar could Ant-Man walk before the plank starts to rotate?

The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center ( Ibar=ml² where l is the length of the bar). When the skater's hands and arms are brought in and wrapped around their body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. The hands and arms have a combined mass 10 kg. When outstretched, they span 2.1 m. When wrapped, they form a cylinder of radius 21 cm.
