Answer:
(a) 625 ft lb
(b) 468.75 ft lb
Explanation:
Work=Force* Distance
(a)
Force=wl/2 where w is uniformly distributed load of 0.5 lb/ft and l is the length of the rope
Force=0.5*50/2=12.5
Work=12.5*50=625 ft lb
(b)
Assuming that the weight of the rope is concentrated in two places, half is 12.5 feet down and the other half is 37.5 feet down. The center of mass of the top half is 12.5 feet down. The weight of the top half is 12.5
Work=work on top half + work on bottom half
Work on top half=12.5*(0.5*25)=156.25 ft lb
work on bottom half=12.5*(0.5*50)=312.5 ft lb
Total work=156.25+312.5=468.75 ft lb
