You may use the normal assignment operator to assign a variale the result of a symbolic evaluation. Or is the question meant how to get the positive result only?

You have not used a solve block, as your subject pretends. You wouldn't experience the problem if you had used a solve block as you could use constraints in a solve block.

With the symbolics you may either use "assume" to tell muPad that all variables (units are seen by the symbolics as unknown varaibles, too) are positive

or you may assign the symbolic result to a variable and then pick the correct solution yourself using the vector index

You're solving for the torque at which the part fails. The units need to be ft lbf, not psi.

Assign the result of the symbolic result to a variable, extract the element you want and then change the Result display format to Decimals = 0 and Exponential Threshold = 5 (or some suitably large number to stop the exponent displaying).
