Problem 13.11: Determine where the normal force acts on a box on a ramp

Please wait for the animation to completely load.

A wood block of uniformly distributed mass sits in equilibrium on a ramp as shown in the animation. Its mass is 0.20 kg (position is given in meters). Restart.

  1. If you replace the "load" of the ramp on the bottom surface of the block with a single normal force acting at a certain distance from the front edge of the block, what are the magnitude and direction of this force and at what location does the force act?
  2. What is the force of static friction on the block?
