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.
