Question
A horizontal force F shown in the figure is exerted on a vertical lever to prevent a load (weight W) from falling downwards. The drum can rotate without friction about point B; the coefficient of static friction between the drum and the block is μ0=0.30. Determine the magnitude of the force F (in kN) needed to prevent the drum from rotating.
a= 4m
b=3m
c=1m
diameter of the drum = 4m
