Chapter 8, Problem 7MCQ

To determine

The magnitude of the force ${\overrightarrow{F}}_1$ such that the object is in equilibrium, from the given options, when the lower arm of the object is subjected to a constant force ${\overrightarrow{F}}_2$ as shown in the figure:

(a) $F_1=F_2$

(b) $F_1=\sqrt{2}{F}_2$

(c) $F_1=\frac{\pi }{2}{F}_2$

(d) $F_1=2F_2$

(e) $F_1=0$

(f) The object cannot be in equilibrium no matter how large the force $F_1$ is.
