23. A jaw force of 100 lb is required to hold onto a bolt. The pair of pliers has a handle
length of 3 in. (i.e., the length from the pin to the handle force) and a jaw length of 1/2 in.
(i.e., the length from the pin to the jaw force). How much input force is required?
24. A 1/2 in. diameter bolt will be "cut" with an applied force from a bolt cutter of 2000 lb.
If the handle force that can be generated is a maximum of 100 lb, what minimum handle
length is necessary if the jaw length is 11/2 in.?
