A differential wheel and axle is used to lift a box of mass 400kg. The larger and Smaller radii of the beam
are 40cm and 30cm respectively. The length of the Crank
arm is 50cm. If the efficiency of the machine is 80%
Determine the motive force required to lift the load-
Velocity Ratio and Mechanical Advantage gained

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

it was given as a lesson and guide for prayer.
