Question

Which one of the following is NOT true for couple acting on a steering wheel?

A. ƩF = 0 ⃝ B. Ʃτ = 0 ⃝

C. Ʃτ ≠ 0 ⃝ D. Ʃa = 0 ⃝​

Answer 1

Answer:
Option B is the answer . Sigma torque is equal to zero .
Explanation:

Answer 2

Option (B) ∑τ = 0, is the one not true for a couple acting on a steering wheel.

• A couple generates when two same forces are applied parallelly in the opposite direction.
• The couple can be defined as a twisting force that makes an object turn.
• The force applied by the car driver to turn the steering wheel is the couple.            
• In a couple, the total net force quantity is zero as the two forces are applied in opposite directions.
• The acceleration depends on the net force applied since in a couple the net force is zero net acceleration also will be zero.
• But, the torque value or the moment is the multiplication result of one force size and the perpendicular distance between two forces.
• So, the net value of torque can't be zero in a couple.
