(OP)
how do I calculate how much force is necessary to prevent metal from expanding because of a temp. rise?

RE: If it's possible,
Castigliano's method for calculating forces is an application of his first theorem, which states:
If the strain energy of an elastic structure can be expressed as a function of generalised displacement qi; then the partial derivative of the strain energy with respect to generalised displacement gives the generalised force Qi.

RE: If it's possible,
Thanks, I'll pursue this.
RE: If it's possible,
S=E*e which can be in this other form
F/A=E*dl/L
S=compressive or tensile stress;E=modulus of eleasticity;e=strain;F=force; A=cross sectional area;dl= increase or decrease in length;L=original length before heating or cooling.

RE: If it's possible,
This last one I must have learned at some point.
I guess I didn't apply it to other than textbook problems, and by the time I needed for the real world, I forgot I knew it.
Or some such thing. . .?
