Final answer:
Torsion or twisting is the load that causes another object to twist. When a force is applied to one end and the other end is fixed, it creates a torque, resulting in the object twisting or rotating.
Step-by-step explanation:
Torsion or twisting is the load that is imposed in a manner that causes another object to twist. When a force is applied to one end of an object and the other end is fixed, it creates a torque or twisting force, which causes the object to twist or rotate.
For example, when you twist a towel to wring out water, you are applying torsion or twisting force to the towel. The towel twists or rotates due to the torque created by your hand.
Similarly, when you twist open a bottle cap or tighten a screw with a screwdriver, you are applying torsion or twisting force to the cap or screw, causing it to twist or rotate.
