ƩFx=0
ƩFy=0
ƩM=0
The Attempt at a Solution
For the entire frame:
ƩMA = 0: -360*15 -240*33 + E*12 = 0
E = 1110 lb →
ƩFx = 0: 1110 - Ax = 0
Ax = 1110 lb ←
These are the correct values so far.
Member BC:
By = (4/3)*Bx
ƩMC=0: -240*9 + 360*9 + Bx*12 - (4/3)*Bx*18 = 0
Bx = 90 lb
By = (4/3)*90 = 120 lb
These values are incorrect.
