Question

(b) Figure below shows a device used for compressing crushed material. 380 mm 120 mm lever arm plunger 20N cylinder crushed material cross-sectional area A The lever arm rotates about the hinge H at its right-hand end. A force of 20 N acts downwards on the left hand end of the lever arm. The force F of the crushed material on the plunger acts upwards. Ignore the welght of the lever arm. () Use the clockwise and anticlockwise moments about H to calculate the upward force F which the crushed material exerts on the plunger. The distances are shown on the figure. [3] at he​

Answer 1

Answer:

clockwise Force *dist= Force *dist(total)

F*120mm=20*500mm

F=20*500/120
