A worker wants to turn over a uniform, 1250-N, rectangular crate by pulling at 53.0° on one of its vertical sides (Fig. P11.69). The floor is rough enough to prevent the crate from slipping. A) What pull is needed to just start the crate to tip? B) How hard does the floor push upward on the crate? C) Find the friction force on the crate. D) What is the minimum coefficient of static friction needed to prevent the crate from slipping on the floor? Pul

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.
