Two blocks A and B are connected by a horizontal bar whose mass is negligible. The mass of block A is 100-kg and the mass of block B is 50-kg. What force P will just prevent the blocks from slipping down the plane?The coefficient of friction between block A and the inclined surface is o.20, while that of block B and the inclined surface is 0.30.
A particle, of mass 6 kg, is in equilibrium on a rough horizontal plane under a force of magnitude T N, which acts at an angle 15 above the horizontal. Given the coefficient of friction between the particle and the rough horizontal plane is 0.35, what values could T take?
Logs weighing 1.3 kg and 2.2 kg lie on a flat surface and are connected by a rope that breaks at a force of 20 N. The coefficient of friction between the lighter log and the base is 0.50, and between the heavier log and the base 0.30. With what maximum force can we pull the lighter log so that the string does not break?
