Ahelical compression spring is wound using 2.5-mm-diameter music wire. the spring has an outside diameter of 31 mm with plain ground ends, and 14 total coils. (a) estimate the spring rate. (b) what force is needed to compress this spring to closure? (c) what should the free length be to ensure that when the spring is compressed solid the torsional stress does not exceed the yield strength? (d) is there a possibility that the spring might buckle in service?

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
