A crane has a mass of 4000kg and a base of 3.4 m. The arm of the crane is 22m and attaches to the center of the crane. IF the arm is placed at an angle of 30 degrees, what is the largest mass that the crane can hold off the ground without tipping? I keep getting 4000 kg. I place my fulcrum at the center of the crane arm. Can someone help me with this problem. The only thing I am having trouble with is placing the pivot point? why can it not be at the center of the crane arm?
