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.

Chapter 10, Problem 44P

A 9.0 m uniform beam is hinged to a vertical wall and held horizontally by a 5.0 m cable attached to the wall 4.0 m above the hinge, as shown in Figure 10.62. The metal of this cable has a test strength of 1.00 kN, which means that it will break if the tension in it exceeds that amount. (a) Draw a free-body diagram of the beam. (b) What is the heaviest beam that the cable can support with the given configuration? (c) Find the horizontal and vertical components of the force the hinge exerts on the beam.

Hi, I am in physics I and I'm trying to understand this word problem. It saids that a 6.0-m uniform board is supported by two sawhorses 4.0m apart. A 32kg child walks on the board to 1.4 m beyond the right support when the board start to tip. a.) Find the mass of the board b.) Then he walks back 0.40m and stands still. Find the forces exerted by the supports at this time. (use the mass found in part a). Please be detailed of how this works. Its a harder problem for me to understand. Thank you!

A 5.0 kgkg plank is being held up in a horizontal position by a rope as shown in (Figure 1). The plank is 1.0 mm long, and its left end is attached to the wall by a hinge. A 10 kgkg box is placed on the plank at a distance x� from the hinge. If the maximum tension that the rope can sustain is 48 NN, what is the maximum value of x� before the rope breaks?

A uniform 8.0-m, 1500-kg beam is hinged to a wall and supported by a thin cable attached 2.0 m from the free end of the beam, as shown in the figure below (Figure 1). The beam is supported at an angle of 30.0 ∘ above the horizontal. Make a free-body diagram of the beam. The beam attaches to the wall via a hinge at dot A. The middle of the beam is indicated by dot B. The cable attaches to the beam at dot C
