The machine shown is used to move boxes. Bar ABC slides horizontally in the bearing of the fixed machine housing. Points, B, C, and D are pins, and point C has a frictionless roller. The flywheel E rotates clockwise under the action of moment Me. The horizontal surface on which the boc rests has coefficients of friction Ms=0.3 and Mk =0.25, and all other contact surfaces are frictionless. If the box weighs 900N, determine the moment Me that must be applied to the flywheel to initiate motion of the box, and determine if the motion is sliding or tipping.
