Assume you get a summer job as a crane operator. on the first day you are lifting a heavy piece of machinery. even though you have the arm at 70∘ above the horizontal, the crane begins to tip slowly forward. consider the following possible actions: release the brake on the lifting cable so that the load accelerates downward. release the lifting arm so that θ decreases rapidly and the load accelerates downward. increase θ while simultaneously letting out the lifting cable so that the load accelerates downward. put the crane wheels in gear and accelerate the crane forward. none of these solutions is ideal, but which will have the short-term effect of restoring contact of the crane's rear wheels with the ground? a) all but 1 b) all but 2 c) all but 3 d) all but 4 e) all of them
