Two blocks A and B are kept in equilibrium with the help of rod of negligible weight as shown in Fig. NP 4.5. The coefficient of friction between block A and horizontal plane is 0.36 and between block B and inclined plane is 0.30. Determine the minimum weight of block A which can hold the system in equilibrium.
