Analysis of truss by method of joints. 

Assignment # 6: Analysis of Truss by Method of Joints 1. Determine the force in members CE, CF and BF for the truss loaded as shown. Ans. BF = 0.289P (T) 300 \60° 30° OF H. 45 45° 2. The truss is subjected to four loadings as shown. Calculate the axial force in members BD, CD, and CE using method of joints. Ans. BD = 948 lb (C), CD = 141.4 Ib ( T ) 1200 lb 600 lb D 20' 15' 15' 15' E F 10' 400 lb 200 lb 3. The truss is loaded by a 4-KN force and a 5-KN force applied at B and A, respectively. Determine the magnitude of axial force developed in members CE and CF. Ans. CF = 8.77 kN 4 kN -3 m- -3 m- 3m- 3 m 5 m 5 kN
