To lift the same load, Machine P requires an effort of 100 N, while Machine Q requires an effort of 50 N. Which machine has the greater mechanical advantage?
Machine Q
Mechanical advantage (MA) = load ÷ effort.
Both machines lift the same load, so the machine that needs less effort has the greater MA.
Machine Q needs 50 N and Machine P needs 100 N, so Q's MA is twice P's.
Hence, the answer is Machine Q.
