A uniform L = 6.71 m long horizontal beam that weighs WB= 363N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cablewith tension Tthat makes an angle of 50.0° with the horizontal, and a person of weight WP= 427.5N is standing d = 2.38m from the pin. Find the magnitude of the force R exertedon the beam by the wall if the beam is in equilibrium. A)532N B)534N C)536N D)538N
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.
