Ahollow steel [e = 30,000 ksi] tube (1) with an outside diameter of 3.250 in. and a wall thickness of 0.375 in. is fastened to a solid aluminum [e = 10,000 ksi] rod (2) that has a 1.750-in.-diameter and a solid 1.125-in.-diameter aluminum rod (3). the bar is loaded as shown. assume l1 = 70 in., l2 = 40 in., l3 = 27 in., r = 35 kips, q = 16 kips, and p = 28 kips. determine (a) the change in length of steel tube (1). (b) the deflection of joint d with respect to the fixed support at a. (c) the maximum normal stress in the entire axial assembly.

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

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?
