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

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
