A cast iron beam 12m long and supported as shown carries a uniformly distributed load of intensity wo, N/m, (including its own weight). The allowable stresses are ??? ≤ 25 MPa and ??? ≤ 90 MPa. Determine the maximum safe value of wo, in N/m, if x= 1.2m.

Topic: Singly Reinforced Concrete    A simply supported concrete beam 6m long is reinforced with four-28mm diam. tension barss. The beam has a width of 300mm and overall depth of 400m. The steel covering to the centroid of the reinforcements is 70mm, fc’= 30 MPa and fy= 418 MPa.   A. Draw the stress diagram. B. Compute for the Ultimate capacity of the beam   Note: Don’t conclude compression bars.

A simply supported wood beam with overhang is subjected to uniformly distributed load q. 9 1m- 250 mm 200 mm i The beam has a rectangular cross section with width b = 200 mm and height h = 250 mm. Determine the maximum permissible value q if the allowable bending stress is all = 11.8 MPa, and the allowable shear stress is Tall = 1.95 MPa.
