You have just bought a used car engine from your local scrap dealer and are thin

Question

You have just bought a used car engine from your local scrap dealer and are thinking of borrowing your neighbor's wheelbarrow to move it into his garage, which you have already borrowed to fix your car. The engine weighs 143 kg and you estimate, from the geometry of the wheelbarrow and of the engine, that the center of mass of the engine will be about 35.0 cm from the center of the wheel of the wheelbarrow. What will be the magnitude of the torque, in N-m, of the engine about the center of the wheel? Assuming that the wheelbarrow itself has negligible weight, what will be the total force you must apply on the two handles, in N, if the handles are 185 cm from the center of the wheel?

Explanation / Answer

divide your first torque which is t = mg * r that's torque one for force do torque divide by new radius in m
