To understand the role of friction in a state of equilibrium.
A chair weighing 145 N rests on a level floor that is not frictionless. A man pushes on the chair with a force F = 36.0 N that is directed at an angle of 38.0 ∘ with the horizontal.
(Figure 1) Assume that the chair is stationary but is on the verge of sliding.

Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N, but friction prevents the crate from sliding. Part A Draw a free-body diagram of the crate. Part B What is the magnitude Fp of the minimum force you need to exert on the crate to make it start sliding along the floor? Let the coefficient...

Learning Goal: To be able to find the center of gravity, the center of mass, and the centroid of a composite body. A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids. An object is made from a uniform...
