I 450 m P R=? R = ? (Q1) N N N (Q2) 1. For the truss shown in Q1 above, determine the magnitudes of the forces present in all truss members. Use a method of joints approach. (20 points) 2. Qualitatively determine the force characteristics for the truss shown in Q2 above. Additionally, identify the members in the upper and lower chords with the largest tension and compression forces. Use the method of sections to determine the magnitude of the member with the largest tension force and the magnitude of the member with the largest compression force. (10 points)
