Problem Statement: EE Board October 1997
A 250 lb. block is initially at rest on a flat surface that is inclined at 30°. If the coefficient of kinetic friction is 0.30 and the coefficient of static friction is 0.40, find the force required to start the block moving up the plane.
- A. 190 lb.
- B. 212 lb.
- C. 125 lb.
- D. 75 lb.
The force required to start the block moving up the plane is 212 lb..Solution:
