1. Identify all zero force members in the trusses shown. (12.5 pts each). P A A) 60 60 k B) ok A 133.33 k 15 ft 66.67 k 15ft

Solution

A) To identify zero force members take the joint and apply equilibrium equations.

In this truss all zero force members: BG, CH, KE, EJ, KJ, DE, DJ, IJ, CD, ID

B) All Zero force members: BH, FL,FK, KE, EJ
