TD5/1: VECTOR GEOMETRY – TRUSS ANALYSIS ASSIGNMENT

SELF ASSESSMENT EXERCISE

1. Solve the forces in the frameworks below and determine which are ties and which are struts

Note that the rollers ensure R2 is vertical.

(Ans. b-c 450 N strut, c-a 370 N strut, d-c 317 N tie, R1=183 N R2= 317 N)

2.

Answers

R1 = 5.75 kN, R2=7.25 kN.

b-c 7.25 kN tie, a-c 10.25 kN strut, d-g 6.5 kN strut, c-d 1 kN strut.

e-f 8.2 kN strut, d-e 1kN tie, e-b 5.7 kN tie)
