LIFESAVOR RATING FOR CORRECT ANSWER!!!!
Learning Goal: To step through the application of to prevent a crane from tipping over. A crane of weight has a length (wheelbase) , and its center of mass is midway between the wheels (i.e., the mass of the lifting arm is negligible). The arm extending from the front of the crane has a length and makes an angle with the horizontal. The crane contacts the ground only at its front and rear tires.
Given the angle , what is the maximum weight (or load) that this crane can lift without tipping forward? (Recall that weight has units of force.)
Express the maximum load in terms of and other quanitites given in the problem introduction.
