1. Conditions of Static Equilibrium of a Rigid Body

Statics is the branch of physics which studies the conditions of equilibrium of a body at rest. It is assumed that the bodies remain perfectly rigid when a set of forces and torques act on them. What is the condition of translational equilibrium? What is the condition of rotational equilibrium? What are degrees of freedom? What is their relation to the number of conditions of equilibrium? What is a statically indeterminate problem? The video lecture “Conditions of Static Equilibrium” answers some of these questions, and more.

4. Equilibrium of a Leaning Ladder

A uniform ladder rests on a rough floor and leans against a smooth wall. Do the forces acting on the ladder lie in the same plane? What is the number of degrees of freedom? What is the number of independent equations? At what minimum angle may the ladder remain inclined without slipping? If the wall is rough as well, can we find all the unknowns?The video lecture “Equilibrium of a Ladder” answers some of these questions, and more.
