A homogeneous board weighing 274 N and long L = 6.23 m rests on a wall of height h = 2.87, the upper corner of which has a frictionless rolling mechanism. The plate is in equilibrium for any theta angle greater than or equal to 68.0 °, but it slides as soon as the angle is less than 68.0 °. Find the coefficient of static friction between the board and the floor.
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.
