Question 1: A 45-N vertical force P is applied at A to the bracket shown, which is held by screws at B and C. (a) Replace P with an equivalent force-couple system at B. (b) Find the two horizontal forces at B and C that are equivalent to the couple obtained in part a.

(a) For the configuration in Prob. $4.5,$ calculate the force on $\mathbf{p}_{2}$ due to $\mathbf{p}_{1},$ and the force on $\mathbf{p}_{1}$ due to $\mathbf{p}_{2}$. Are the answers consistent with Newton's third law? (b) Find the total torque on $\mathbf{p}_{2}$ with respect to the center of $\mathbf{p}_{1}$, and compare it with the torque on $\mathbf{p}_{1}$ about that same point. [Hint: combine your answer to (a) with the result of Prob. 4.5.]
A pair of forces with equal magnitudes, opposite directions, and different lines of force is called a "couple." When a couple acts on a rigid object, the couple produces a torque. The diagram shows a couple acting on a tire wrench, each force being perpendicular to the wrench. What is the magnitude of the torque about point B if F = 320 N and L = 60 cm? N · m
