Chapter 8, Problem 20P

To determine

The force required to push down on the handle so that the lever exerts a force of magnitude $8000\text{ N}$ to lift the back of a car which has got a flat tire, if the home made lever has a very light, $1.6\text{ m}$ long handle that is pushed down at right side of the fulcrum. The back of the car is supported at $0.10\text{ m}$ from the left side of the fulcrum.
