A block of mass m is resting on a wooden plank. A hinge at one end of the plank allows the opposite end to be raised, creating an angle, θ , with respect to the horizontal, as shown. The coefficient of static friction between the block and the plank is μs , and the coefficient of kinetic friction is μk . Given m= 2.93kg , θ= 14.9∘ , μs= 0.91 and μk= 0.33, what is the magnitude, in newtons, of the friction force on the block?
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.
