1) For the below given Gerber type bridge truss system, calculate the values of internal forces for the marked truss elements: \( V_{1}, U_{2}, O_{5}, V_{4}, U_{5}, U_{7} \), and \( D_{5} \). 2) For the system illustrated below, \( 1 k N \) vertical concentrated load moves through points A-C-D. Plot the influence line diagrams for \( V_{A}, M_{1}, T_{2}, M_{3} \), and \( N_{4} \).
