Concept

Problem: YOU hold a picture motionless against a wall by pressing on it.Identify all forces acting on the object and draw the free-body diagram.Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.

FREE Expert Solution

The forces that will be acting on the picture are:

  • The force exerted by the hand, F.
  • The reaction force by the wall, n.
  • The friction force, ffr.
  • The weight of the picture, w.
