PART B
Answer any two full questions, each carries 15 marks.
a) Explain the effect of temperature change in any member of an indeterminate
truss.
b) Determine the support reactions of the beam shown in fig. using the method of

consistent deformation.

a) Three wheel loads, each of magnitude W, are traversing a simply supported beam
from left to right. If the distance between consecutive wheel loads is a and span
of the beam is 2/, determine the maximum bending moment at mid-span of the
beam. Given, a= 4

b) A UDL 2kN/m of length 1.5 m is traversing a simply supported beam of span
8m. Determine i) the maximum support reaction ii) Maximum shear force at a
section 2m from left support. In both the cases, indicate the position of the UDL
on the span.

a) Analyse the frame shown in figure using strain energy method.
