A beam 10 m long is simply supported 1 m from each end. It is made of two C 380 x 50 channels riveted back to back and used with the webs vertical. Determine the total uniformly distributed load (KN/m) that can be carried along its entire length without exceeding flexural stress of 120 MPa. -C 380 X 50 W N/M A B R

Question 1 A composite beam ıs constructed from a wood beam (75 mm wide, by 150 mm hıgh) and a steel plate 75 mm wide The wood and the steel are securely fastened to act as a single beam Calculate the required thickness of the steel plate if the allowable compressıve stress ın 11 the wood is 14 MPa and allowable tensıle stress in the steel plate is 110 MPa GIven that the composite beam is subjected 1 2 to a positive bendıng moment M 8.5 kN.m, calculate maximum bending stress in the wood Assume that Ew 11 GPa and Eg = 200 GPa.
