Each of the links AB and CD is made of aluminum (E = 10.9 106 psi) and has a cross-sectional area of 0.2 in. Knowing that they support the rigid member BC, determine the deflection of point E if P = 1.4 kip. (Round the final answer to two decimal places.) 18 in. A B 10 in. E 22 in.. The deflection of point E is D 7.5 x 10-3 in. . 2. A polystyrene rod consisting of two cylindrical portions AB and BC is restrained at both ends and supports two 7-kip loads as shown. Take E= 0.45 x 106 psi. 25 in. 15 in. P A References value: 10.00 points -1.25 in. P B C Section Break 2 in. eBook & Resources Difficulty: Medium Determine the reactions at A and C. (Round the final answers to two decimal places. You must provide the answers before moving to the next part.) The reactions at A and C: RA = -2.28 kips Rc = 9.724 kips t >>>> Required
