Question 4

The shape factor for the steel beam section shown in the figure below, is _________.

Question 5

Rectangular section of width b and depth h is stressed up to fy upto a depth of h/4 from both top and bottom fibres under the action of moment M, magnitude of M is – x.(fyb1h2), value of ‘x’ is -

Question 6

What is the ratio of collapse load in a fixed bean of length ‘L’ subjected to point load at centre to the collapse load in a propped cantilever beam of half the length and double the point load at the centre? Assume ‘MP’ to be same for both beams.
