Consider the figure below. (Let w, = 150 N and w, = 51.5 N.) W (a) What is the minimum force of friction required to hold the system of the figure abdve in equilibrium? (b) What coefficient of static friction between the 150-N block and the table ensures equilibrium? (Enter the minimum acceptable coefficient of friction.) (c) If the coefficient of kinetic friction between the 150-N block and the table is 0.172, what henging weight should replace the 51.5-N weight to allow the system to move at a constant speed once it is set in motion?

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.
