The steering of a car has a radius of 16 cm. Find the torque produced by a couple of 50 N. (16 Nm)
Difficulty: Easy
Solution:
Radius = r = L = 16 cm =$\frac{16}{100}$ m = 0.16 m
Couple arm = L = 16 cm =$\frac{16}{100 }$ m = 0.16 m
Force = F = 50 N
Torque Τ = ?
Torque Τ = $F \times L$
= $50 N\times(2 \times 0.16)$
= 16 Nm
