The wooden strut is subjected to the loading shown. Draw the state of stress at point C on an infinite small element. The strut is supported by a bolt (pin) at point B and a roller support at point A. 50N S0N 40N 40 N -60 100 mm 50 mm 25 mm 200 mm 200 mm'200 mm'200 mm 100 mm 100 mm

A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 45 ft-kips, and the maximum moment for the service live load is 63 ft-kips (these moments occur at the same location on the beam and can therefore be combined). a. If load and resistance factor design is used, determine the maximum factored bending moment (required moment strength). What is the controlling AISC load combination? b. What is the required nominal moment strength for a resistance factor of 0.90? c. If allowable strength design is used, determine the required moment strength. What is the controlling AISC lead combination? d. What is the required nominal moment strength for a safety factor of 1.67?

Compute the nominal shear strength of an M107.5 of A572 Grad 65 steel.

Verify the value of Zx for a W1850 that is tabulated in the dimensions and properties tables in Part 1 of the Manual.
