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...

A chair of weight 70.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 45.0 N directed at an angle of 42.0 ∘below the horizontal and the chair slides along the floor. Using Newton's laws, calculate n, the magnitude of the normal force that the floor exerts on the chair. Express your answer in newtons.

A 110 N force, directed at an angle θ above a horizontal floor, is applied to a 24.0 kg chair sitting on the floor. If θ = 0°, what are (a) the horizontal component Fh of the applied force and (b) the magnitude FN of the normal force of the floor on the chair? If θ = 31.0°, what are (c)Fh and (d)FN? If θ = 55.0°, what are (e)Fh and (f)FN? Now assume that the coefficient of static friction...
