2. For the truss shown in Fig. (a), calculate the normal stresses in (1) member AC; and (2) member BD. The cross-sectional area of each member is 900 mm². 3. Figure (a) shows a two-member truss supporting a block of weight W. the cross-sectional areas of the members are 800 mm² for AC. Determine the maximum safe value of W if the working stresses are 110 MPa for AB and 120 MPa for AC.

The truss $A B C$ shown in the figure supports a horizontal load $P_{1}=1.3 \mathrm{kN}$ and a vertical load $P_{2}=4 \mathrm{kN}$ Both bars have cross-sectional area $A=1500 \mathrm{mm}^{2}$ and are made of steel with $E=200 \mathrm{GPa}$ (a) Determine the strain energy $U_{1}$ of the truss when the load $P_{1}$ acts alone $\left(P_{2}=0\right)$ (b) Determine the strain energy $U_{2}$ when the load $P_{2}$ acts alone $\left(P_{1}=0\right)$ (c) Determine the strain energy $U_{3}$ when both loads act simultaneously.

The truss, given below, is subjected to the forces shown: 1) Determine the force in each member of the truss and state if the members are in tension or compression if P1 = 3 KN and P2 = 2 KN. Don't forget to draw FBD of each joint while solving. 2) Find the reactions at the supports A and E.
