Question

The diameter of a steering wheel is 60 cm. The couple applied on the wheel when two equal and opposite forces of 10 N is applied on the rim of the wheel is:

Options

• 4 N m

• 6 N m

• 8 N m

• 60 N m

Answer 1

6 N m

Explanation:

Force (F) = 10 N

Diameter (Arm of the couple, d) = 60 cm = 0.6 m

Moment of Couple = Force × Arm of the couple

= 10 N × 0.6 m

= 6 N m
