PARTA
Answer any three full questions. Each question carries 10 marks.

1 Determine forces in the member CF, FC, CD and FD using method of joints. 10

2 Derive Clapeyron’s 3 moment equation for a continues beam with constant 10
flexural rigidity.
3 a) Explain strain energy density due to axial loading using stress-stain diagram. 3

b) A slightly tapered bar AB of rectangular cross section and length 1. is acted upon 7
by an axial force P (see figure). The width of the bar varies uniformly from 22 at

end A to ‏رط‎ at end தீ. The thickness / is constant. Find the strain energy of the bar.
