A block is resting on a wooden plank. There is a hinge on one end of the plank which allows the other end to be lifted to create an angle, 0, with respect to the horizontal as shown in the figure. The coefficient of static friction between the block and the plank is μg. torce. O Part (a) Please select the correct Free Body Diagram, where F is the force due to gravity, F is the normal force, and F is the static friction F $ F₁ F L F f m F y Ꮎ Part (b) The angle is slowly increased. Write an expression for the angle at which the block begins to move in terms of µg. Part (c) If a student measures that the block begins to move at an angle of 0 = 25°, what is the numerical value of the coefficient of static friction,

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.
