A 200 lb box is setting on an inclined plane which has an angle of 30 degrees. The coefficient of static friction in this case is 0.3.

a) What is the force acting normal to the surface of the plane?

b) What is the component of the force of gravity acting down the plane?

c) What is the maximum friction force acting to keep the box from moving?

d) What force is needed to start the box moving up the plane?

e) What force is needed to start the box moving down the plane?
