What is the minimum force that needs to be exerted in order to balance the weight of the engine?
marianne arranges a chain and block pulley to lift a 875 kg engine 1.5 m above its current position in the chasis of a truck. they know that the IMA =10.
the answer is 860 N
can someone please tell me how to get this answer??!
thanks
i cant exactly remember how to solve this one but i think it involves the gravitational force 9.8m/s
N=kg.m/s
