Chapter 8, Problem 26P

(a)

To determine

The force diagram for the beam.

(b)

To determine

The tension in the rope in terms of m, g, and $\theta$.

(c)

To determine

The expression for tension in the rope in terms of ${\mu }_s$, m and g using Newton’s second law of equilibrium.

(d)

To determine

The relationship involving only ${\mu }_s$ and the angle $\theta$.

(e)

To determine

What happens if the angle gets smaller and whether the equation is valid for all values of $\theta$.
