A long bone is subjected to a torsion test. Assume that the inner diameter is 0.375 in. and the outer diameter is 1.25 in., both
for a circular cross section. If E = 16 GPa and v = 0.325, find the largest torque that can be applied prior to yield, where σ yield = 1.25 ksi (i.e., a maximum normal stress).

Answer:
q=39.15 W/m²
Explanation:
We know that
Thermal resistance due to conductivity given as
R=L/KA
Thermal resistance due to heat transfer coefficient given as
R=1/hA
Total thermal resistance
Now by putting the values
We know that
Q=ΔT/R
So heat transfer per unit volume is 39.15 W/m²
q=39.15 W/m²
