Question 4 A uniform rod AB of weight W and length 2a, rests in equilibrium with its end A against a smooth vertical wall PQ, and its end B on a rough inclined plane OQ at an angle a from the horizontal as shown in Figure Q4. The rod makes an angle B with the wall, where tan ß- 0 (a Draw the force diagram, indicating all the forces acting on the rod AB (3 marks) (b) Apply vectors, write down the equations for all the forces acting on the rod AB and its position vectors from B (3 marks) (c Apply equilibrium principles and use torques about B to ensure the following: (i) solve the magnitude of the normal reaction NAl on the rod at A, in (3 marks) ii) sve the magnitude of the frictional force FB and the normal reaction 4 marks) terms of W NBI on the rod at B, in terms of α and W Answers: 4.
