Determining the Most Efficient Machine
Calculate the efficiency for each machine, then answer the question
Machine A has an input work of 1,000 J and an output work of 250 J.
Machine B has an input work of 500 J and an output work of 350 J.
Machine C has an input work of 200 J and an output work of 150 J.
Which machine is the most efficient?
