Calculator The total mark for this section is 38 Q1 Given that tan = A 0 Figure 2 A non-uniform rod AB, of mass 5kg and length 4m, rests with one end A on rough horizontal ground. The centre of mass of the rod is d metres from A. The rod is held in limiting equilibrium at an angle to the horizontal by a force P, which acts in a direction perpendicular to the rod at B, as shown in Figure 2. The line of action of P lies in the same vertical plane as the rod. (a) Find, in terms of d, g and 0, (i) the magnitude of the vertical component of the force exerted on the rod by the ground, (ii) the magnitude of the friction force acting on the rod at A. is 1/1/1 2 (b) find the value of d. 4m B 5 and that the coefficient of friction between the rod and the ground 12 (8) (4)
