Q2.Two steel column P (length L and yield strength fy = 250MPa) and Q (length 2L
and yield strength fy = 500MPa) have the same cross-section and end condition.
The ratio of buckling load of column P to that of column Q is
Q4.Friendship, No matter how ____________ it is, has its limitation
Answer : Option BExplaination / Solution:
Friendship, No matter how intimate it is, has its limitation. Intimate refers to
close personal relations, e.g. an intimate friend. It is also characterized by or
involving warm friendship or a personally close or familiar association or feeling.
Q5.Beam subjected to moving distributed load of 4 kN/m maximum shear force that
can occur just to right of Q is
Answer : Option CExplaination / Solution:
When a cut is made just to the right of Q and displacements are given such that
A’B’ is parallel to B’C’, as B’ is very close to Q, displacement of B’ to the left will
be zero and that to the right will be 1.
Hence slope of B'C' = 1/20 ⇒ Slope of B'A ' = (1/20)×5 = 0.25
ordinate at A ' = (1/20)×5 = 0.25; ordinate at D' = (1/20)×5 = 0.25
If udl is loading span PR, we get maximum SF just to the right of Q
