Question:

A force of $40 \mathrm{~N}$ acts on a point $\mathrm{B}$ at the end of an $\mathrm{L}$-shaped object, as shown in the figure. The angle $\theta$ that will produce maximum moment of the force about point $A$ is given by:

1. $\tan \theta=\frac{1}{4}$

2. $\tan \theta=2$

3. $\tan \theta=\frac{1}{2}$

4. $\tan \theta=4$
