The bar clamp is being used to clamp two boards together while the glue between them cures. What torque M must be applied to the handle of the screw in order to produce an 80-lb compression between the boards? The-in-diameter single-thread screw has 12 square threads er inch, and the effective coefficient of friction is 0.2. Neglect any friction in the pivot contact at C. Hint: pitch = 1 tooth for every 1/12 inches. Ans: M = 4.12 lb-in 14 www M

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.
