Which twisting force causes rotation?

Which twisting force causes rotation?

• A. Absorption
• B. Torque
• C. Deceleration
• D. Streamlined

Answer: (B)

Torque is the twisting force that causes rotation. When a force is applied at some distance from a pivot, that twisting effect tries to turn the object. The strength of the rotation depends on how large the force is, how far from the pivot you apply it (the lever arm), and the angle between the force and the lever arm. A longer lever arm makes the same force produce more rotation, and a force applied perpendicular to the lever arm yields the greatest twisting effect. This is why using a longer handle on a wrench or door makes it easier to rotate. The other terms aren’t about twisting forces: absorption is taking in material, deceleration means slowing down, and streamlined describes a design that reduces drag rather than causes turning.
