Q1:

A simply supported rolled steel joist 8 m long carries a uniformly distributed load over it span so that the maximum bending stress is 75 N/mm2. If the slope at the ends is 0.005 radian and the value of E = 0.2 x 106 N/mm2, the depth of the joist, is

A 200 mm

B 250 mm

C 300 mm

D 350 mm

E 400 mm

ANS:E - 400 mm

Thanks for explaining @Ranjitha.
