A stick with a mass of 0.215 kg and length 0.440 m rests in contact with one end on a ball and the other on a rough floor. The angle the stick makes with the horizontal is 30.0°. There is no friction between the stick and the ball, but friction with the floor must be accounted for. The force on the stick due to the ball is radially outward (perpendicular to the stick). a) Draw a rigid body diagram representing all forces.
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.
