Please help me with the following question. You can use the second photo as reference and please put the whole process and solution because I’m having a difficulty with understanding it. Thank you very much.
Determine the force in each member.

Transcribed Image Text:METHOD OF JOINTS - PROBLEMS
SOLUTION PROBLEM NO.1
Determine the axial forces in members AB and AC of the
truss.
EF, = A, + B = 0,
3 m
EF, = A, - 2 kN = 0,
EMpoint = -(6 m) A, - (10 m)(2 kN) = 0.
3 m
D
Solving yields A, = -3.33 kN, A, = 2 kN,
B 5m 5 m-
and B = 3.33 kN.
