Note: A one page (one sided) crib sheet is allowed during the quiz,
along with a silent, non-programmable calculator.
Clearly show your work and answer.
The truss shown has the following support reactions:
short link at E = 85.0 k (T), Cx = 59.1 k, Cy = 94.7 k
Using the method of joints only, find:
a) the member forces at joint A [or C or ...]
b) the remaining force at the adjacent joint E [or B or D ...]
c) [some short question from the text material]
Answers:
a) AB = 10.3 k (C), AE = 18.2 k (T) (or BC = 23.5 k (T), CD = 101.2 k (T))
b) BE = 33.2 k (T), ED = 80.3 k (T) (or BD = 63.8 k (C), ED =80.3 k (T))
