| 1 | He used a very sensitive torsion balance. | |
| 2 | I was very pleased with the torsional rigidity of the midsole . | |
| 3 | No monitoring and control requirement on screwing torque. | |
| 4 | If possible, a torque wrench should also be used for tightening. | |
| 5 | So you can immediately see that, of course, the value for kappa-- -- the torsional constant-- is a function of the length. |
