A 387-kg steel beam of length 5.00 m is attached to a wall by a hinge, and kept level by a cable attached to it at a 30.0◦ angle. The maximum tension that the cable can sustain before breaking is 13.0 kN. There is a support that allows a mass to be hung from the beam, three-quarters of the way along its length. (a) What is the maximum mass that can be hung from the beam before the cable snaps? (b) At this maximum mass, what is the magnitude and direction of the reaction force F from the wall against the hinge?
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.
