7. A box of unknown weight is being pulled on a 0 = 39 degree inclined surface by a frictionless pully system attached to a 540 pound box hanging off the pully. The coefficient of static friction between the box and the inclined surface is µ = 0.33 and both boxes are not moving. Answer the questions below: Draw a free body diagram of the box on the incline. Determine the weight (W) of the box on the incline surface. Determine the normal force (N) acting on the inclined box. • Determine the friction force (F) acting on the inclined box.
