smooth horizontal ground and its end B against a rough vertical wall. The coefficient of friction between the ladder and the wall is 1 4. The centre of mass of the ladder is 1.5 metres from A. The ladder lies in a vertical plane perpendicular to the wall and the ground, and is inclined at an angle θ to the horizontal, where tan 2θ= .
Two blocks are connected by a string, as shown in FIGURE 6-44. The smooth inclined surface makes an angle of $42^{\circ}$ with the horizontal, and the block on the incline has a mass of 6.7 $\mathrm{kg}$ . Find the mass of the hanging block that will cause the system to be in equilibrium. The pulley is assumed to be ideal.)
