Determine the maximum torque that can be applied at 1.0 m from the right end of the shaft, without causing excessive rotation.
Problem: A frame consists of two bars joined rigidly at B and built in
at A and C (see Figure). Determine the bending moment M at B
and the compressive force P in AB when, due to a rise in temperature,
the bar AB increases in length by 
Answer. P and M can be found from the equations:

please see this,,, sir/madam,,, why is it in problem 206

Good day. May I ask if the 900 lb load in C is really downward? I think it is upward to maintain the shear of the 900 right? If it would be downward then the shear will be zero? Correct me if I'm wrong. Thanks!
Sir, could you explain why the deformation due to load & temperature of brass & copper are subtracted instead of being added?
