Total load=60kg or 600NLoad arm=70cm=0.70mEffort arm=70+50=120cm=1.20mNow,Load x load arm=Effort x Effort arm600 x 0.70=E x 1.20E=350NNow work done =350 x 0.50=175JRegards,Nirmal SinghAskiitians Faculty
Total load=60kg or 600N
Load arm=70cm=0.70m
Effort arm=70+50=120cm=1.20m
Now,
Load x load arm=Effort x Effort arm
600 x 0.70=E x 1.20
E=350N
Now work done =350 x 0.50=175J
