The aluminum rod (E_1 = 75 GPa) is reinforced with the firmly bonded steel tube (E_2 = 209 GPa). The diameter of the aluminum rod is d = 28 mm and the outside diameter of the steel tube is D = 42 mm. The length of the composite column is L = 729 mm. A force P is applied at the top surface, distributed across both the rod and tube. Determine the normal stress sigma in the aluminum rod when P = 97 kN:

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
