Question

Define couple. State any two properties of couple. If the magnitude of either of the forces
forming a couple is 40N and the perpendicular distance between their lines of action is 1.5m.
Find the magnitude of the torque​

Answer 1

Explanation:

• coupl =when 2 non-coliner forces of equal magnitude and opposite direction act on system then such a system is called couple

Answer 2

Two equal, opposite, parallel forces act on a body at different line and also gives turning effect is called couple.

Equation of magnitude of torque:

τ = r × F

Values:

i) 0° = Torque is zero

ii)90° = Torque is maximum that is 90°
