The problem and diagram is given on the sheet.
Homework Equations
sigma Fx=0
sigma Fy=0
The Attempt at a Solution
Starting freebody from point B
T=tension, C=compression
TBC = cos36.86deg = 3250N cos22.62deg
TBC = 81.39N
CBE = 81.39sin36.86deg + 3250sin22.62deg
CBE = 1.3KN
Now using Freebody at point C
TDCcos45deg = 81.39cos36.86deg
TDC=92.09N
M=92.09sin45deg + 81.39sin36.86deg
M=113.94N [FINAL ANSWER]
am i doing this correctly? did i make a mistake anywhere? I have a test tomorrow i need to know if i am missing some fundamental knowledge.
thank you for taking the time to help me.
