4 - For the beam loading configuration and cross-section shown below, what is the maximum allowable load P given that the maximum allowable stress (in tension and compression) is 120 MPa?

Determine the maxinum tensile stress and compressive stress for the beam with the given cross section. Show your complete solution.

Tow square bars are welded together and loaded axially as shown: Determine The normal stress between A&B The normal stress between B&C The normal stress between C&D The total change in length of the bar Assume : w1 =40 mm, w2 = 50 mm, P1 = 130 kN, P2= 65 kN, and P3 =260 kN.  E = 200,000 Mpa original lengths LAB = 100 mm, LBC = 120 mm, and LCD = 130 mm,

I saw this question solved before, both on Chegg and Bartleby and it was WRONG! Please,if you do not know how to solve DO NOT COPY the wrong solution.Thank you!
