Chapter 3.1, Problem 3.2P

(a)

To determine

The moment produced by the weight $\left(M_E\right)$ of the crate about E.

(b)

To determine

The smallest force ${\left(F_A\right)}_{\min }$ applied at A that creates a moment of equal magnitude and opposite sense about E.

(c)

To determine

The magnitude, sense and point of application on the bottom of the crate of the smallest vertical force ${\left(F_{\text{vertical}}\right)}_{\min }$ that creates a moment of equal and magnitude and opposite sense about E.
