1. (25pts) The truss system is loaded as shown. Support A is an anchored frictionless pin, support G is a frictionless roller. a. Is it stable and statically determinate? 5kN 6kb. Find the support reactions at A 12m and G. Identify an obvious zero force E members and state why (what 7KN criteria) if any are found. 12m d. Using the method of sections only, find the forces in members CB, 10 KN BE, and EF. 12m G
