Question: can somebody solve this i cant seem to get it...

Question details

Table A-9 Shear, Moment, and Deflection of Beams (Contimued) (Note: Force and moment reactions are positive in the directions shown; equations for shear force Vand bending moment M follow the sign conventions given in Sec. 3-2.) 7 Simple supports-uniform load 3 lu tu 24EI 5wl.y Problem Statement: A simply supported beam is subjected to a uniformly distributed load w over its entire length L 1.5 m. The cross section is a square tube as shown in figure (b), with dimensions b 5 cm, h -9 cm, t 0.5 cm. The material has yield strength Sy- 85 MPa Calculate . The distributed load w when the beam yields. Hint ignore the rounded corners. You may use Table A-9(7) Answer tolerance-%. Be sure to include units and sign m needed. Notaton abs(z). All quantities are labeled as positive in the direction shown in the figures. Moment and shear diagrams follow the sign convention described in the textbook.
