Question

Define couple. State the equation of magnitude of torque and state its
values if is i) 0° ii)90°​

Answer 1

Answer:

Couple, in mechanics, pair of equal parallel forces that are opposite in direction. The only effect of a couple is to produce or prevent the turning of a body.

Explanation:

hope it will help you

and sorry because of not telling u the full answer

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°
