Draw a free-body diagram for the rod. (b) What is the tension in the cable? (c) What are horizontal and vertical components of the force exerted on the rod at 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.
As shown on the right, a uniform rod with a weight W= 100 N and a length L = 2.0 m is hinged at the bottom end and is vertical. A light cable, tied to the rod at a height of h = 1.0 m, makes an angle 0 = 40° from the horizontal. A horizontal force F= 50 N is exerted at a height H = 1.5 m on the rod.
(a) Draw a free-body diagram for the rod.
(b) What is the tension in the cable?
(c) What are horizontal and vertical components of
