Please i need a hurry answer please help me
work done on load ... 600 N * 30 m = 18000 J
total work = 18000 J + 200 J = 18200 J
effort distance = 30 m * 6 = 180 m
effort applied = total work / effort distance
total work = 18000 J + 200 J = 18200 J
effort distance = 30 m * 6 = 180 m
effort applied = total work / effort distance
