Q2 : The three bars shown in fig are pined at point B which carry a load P and fixed at points A, C and D. The length of the three bars AB, BD and CB is (L) . The cross section area for each bar is A except the bar CB which has different cross section area of Az. All three bars have the same young modulus E. Determine the axial force in each of the bars.
