Question

A cube with the dimensions bXbXb with mass m lies on the flat horizontal ground. One the side shown in the figure. The thickness normal to the plane of the figure is b. The cube is subject to the earth's gravity and the friction coefficient between the cube abd the ground is mu. Express your answer in terms of the given variables.

  • What is the minimum force required to produce sliding?
  • What is the minumum force required to produce tipping of the cube?
  • Assume the cube is rotating about O. Impulsive horizontal loading L is applied on the edge B such that force F(t) is applied during the very short time delta t: where L= the integral from zero to delta t of F(t)dt. What is the minimum value of the impulse for which the cube tips over and falls on side OA.
