An engineer needs to apply a torque (moment) of 15 Nm to a nut. His spanner is 14 cm long. Calculate the force he must exert on the end of the spanner.
| Data statements | G = 15 Nm r = 0.14 m |
|
| Formula | G = r F | |
| Transposition | F = G / r | |
| Substitution | F = 15 Nm / 0.14 m | |
| Evaluation | F = 110 N | 107.1428... has to be reduced to 2 SF. |
