what is torque and torsion? what is the difference between torque and torsion?

The terms torque and torsion are related to rotational forces, but they describe different concepts:

1. Torque:
• Torque refers to a force that causes an object to rotate around an axis or pivot point.
• It is the measure of the rotational force applied to an object.
• The formula for torque is: τ=F×r×sin⁡(θ)\tau = F \times r \times \sin(\theta)τ=F×r×sin(θ) where τ\tauτ is the torque, FFF is the force, rrr is the distance from the pivot point, and θ\thetaθ is the angle between the force vector and the lever arm.
• Torque is typically used in situations where a force is applied at a distance from a center of rotation (like turning a doorknob or the engine in a car).
2. Torsion:
• Torsion refers to the twisting of an object due to an applied torque.
• It describes the stress and strain experienced by a material when it is subjected to rotational forces.
• Torsion is a deformation that occurs in materials like shafts, rods, or beams when they are twisted around their axis.
• The amount of torsion is typically measured by the angle of twist or the shear stress that develops in the material.

Key Differences:

• Torque is the force causing rotation, while torsion is the effect (the twisting or deformation) that results from torque.
• Torque is a vector quantity, whereas torsion usually refers to a stress or deformation within a material.

In short, torque is the force you apply, and torsion is how that force affects an object.
