Consider Area A = 50 sq.cm = 0.5 sq.m , E = 1

Dsi = m- (2j-3 ) = 6- (8-3) = 1

ΣMa = 0 , Rb * 3 – 15*3 = 0 , Rb = 15 KN

ΣV = 0 , Ra + Rb = 10 , Ra = -5 KN

ΣH = 0 , HD = 15 KN

Convert the indeterminate truss to determinate truss by removing the redundant.

Applying a Unit load in the direction of redundant and analyze the truss.

Find out redundant ,

R = - ΣPKL / ΣK²L
