It is designed to support the two concentrated forces P and 2P (in pound) as shown. Determine the reactions and draw the shear force (1b) and bending moment (lb-in) diagrams in terms of P. Ten 2 in x 2 in x 9 ft lumbers are glued together to form the rectangular beam as shown. What is the maximum allowable force PM“ in lb that may be applied on the beam if (1) the allowable tensile bending stress in the wood is 1800 psi, (2) the allowable compressive bending stress is 1000 psi, (3) the allowable shear stress in the wood is 225 psi, and (4) the allowable shear stress in the gluedjoints is 190 psi? 124g Repeat the same question for the indicated T-beam (the T-beam of Assignment 06). cqulC 022616 an...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
