The plate has thickness of 100 mm. The compression stress in l\/[Pa acting along section a—a is : (a) 10 (b) 50 (c) 20 (d) 100 Answer : 1c] 5) The box beam is constrcted from four boards that are fastened together using nalls spaced along the beam every 3 in> if each nail can resist a shear of 50 lb. The greatest shear force V in Ib that can be applied to the beam without causing failure of the nails is : (a) 211 (b) 317 (c) 323 (d) 485 6) The maximum shear stress in Wa in the web of the beam shown is : (a) 45.78 (b) 36.62 (c) 24.42 (d) 30.52 Answer : 1L)! 7'} Beam iii of steel with E: ,is simply oonneeted ,Izarnesa unifonnlv distributed load erTvl oner its entire length.

### What students are saying

• 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.
