Let theta$2=26\mathrm{.}8$ deg. Using the vector loop method, you determine that theta$3=26\mathrm{.}8$ deg and theta $4=132\mathrm{.}1$ deg.

You can then calculate the transmission angle, $=74\mathrm{.}7$deg.

If the input force is applied at point A and the output force is applied at point $B,$ the mechanical advantage for this position is:

zero.

less than one, but more than zero.

more than one, but not infinity.

infinity.
