Pick up the correct statement from the following:
The bending stress in a section is zero at its neutral axis and maximum at the outer fibres
The shear stress is zero at the outer fibres and maximum at the neutral axis
The bending stress at the outer fibres, is known as principal stress
The planes of principal stresses are inclined at 45° to the neutral plane
All the above.

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
200 mm
250 mm
300 mm
350 mm
400 mm
