Question

Calculate the length of the arm of couple if a force of 13 N produces a moment of couple of 14.3 N m.

Options

• 14.3 × 13 dyne cm

• 14.3 ÷ 13 m

• 14.3 + 13 dyne cm

• 14.3 − 13 dyne cm

Answer 1

14.3 ÷ 13 m

Explanation:

Moment of Couple = Force × Arm of Couple

Arm of Couple = `"Moment of Couple"/"Force"`

= `14.3/13` m
