Equilibrium of Bodies Quiz

1. What is the condition for a body to be in static equilibrium?

The sum of all forces acting on the body must be zero The sum of all moments acting on the body must be zero Both the sum of all forces and the sum of all moments must be zero The body must be at rest

2. A ladder leaning against a frictionless wall is an example of:

Stable equilibrium Unstable equilibrium Neutral equilibrium Not in equilibrium

3. The center of gravity of an object:

Is always at the geometric center Is the point where the weight of the body is considered to act Must be within the physical boundaries of the object Is the same as the centroid for all objects

4. For a body to be in rotational equilibrium:

The net torque about any point must be zero The net force must be zero The body must not be rotating The center of mass must be stationary

5. A book lying flat on a table is in:

Stable equilibrium Unstable equilibrium Neutral equilibrium Dynamic equilibrium
