Q5. The wheel shown in the diagram (Fig. 1.17) has a fixed axle passing through O. The wheel is kept stationary under the action of (i) a horizontal force F1 at A and (ii) a vertical force F2 at B.
(a) Show the direction of force F2 in the diagram.
(b) Which of the force F1 or F2 is greater?
(c) Find the ratio between the forces F1 and F2. Given : AO = 2.5 cm, BO' = 1.5 cm and O'O = 2.0 cm.
The force F1 applied at A produces a clockwise Moment On the wheel it can be balanced by applying the force F2 at B in a direction such that it produces and anticlockwise moment .
therefore the vertical force at B should be applied in the downwards direction as shown in the figure. In equilibrium, F1 ×OA =F2 ×OÓ
