A box that weighs 200N is sitting on an
inclined ramp. The weight is assumed to act at the
centroid of the box. A rope is attached to the box and
passes over a stationary drum. Both of these surfaces
have static friction coefficients as shown in the
diagram.
A) What is the minimum force, P, is required to
prevent the box from moving down the ramp?
B) If the rope were to be cut, would the box slip or
tip down the ramp or would it stay in
equilibrium? Support your decision with all
appropriate diagrams/work/equations necessary.
