Concept explainers

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.

In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder as in Figure P8.92. His 1.60-kg forearm remains in a horizontal position and the strap makes an angle of = 50.0 with the horizontal. Assume the forearm is uniform, has a length of = 0.320 m, .assume the biceps muscle is relaxed, and ignore the mass and length of the hand.

A uniform 5.0 m long 25 kg plank is to hold two people washing windows on a downtown skyscraper. The plank is supported by a rope at each end, and each of the ropes has a breaking point of 1200 N (the maximum tension allowed before the rope breaks). If the mass of the window washer that is standing 1.0 m from the right end of the plank is 85 kg and the second window washer with a mass of 75 kg stands 2.0 m from the left end of the plank, then what are the magnitudes of the tensions in each rope? Do either of the ropes break? Include a force or free-body diagram of the situation.
