difference between torque and torsion in hindi

Torsion means applying a twisting or rotation about the length of an object. A torsion bar is a bar that is twisted along its length, a torsion spring is a coil spring that's twisted along its length. Torque is the amount of twisting force that's applied.

What is difference between torque and torsion?

Torsion happens when the torque causes a shear stress to be applied on the body. The main difference between torque and torsion is that torque describes something that is capable of producing an angular acceleration, whereas torsion describes the twist formed in a body due to a torque.

What is difference between torque and moment?

Difference Between Torque and the Moment

Moment is static force. ... Torque is considered the force that rotates the body about the axis. A moment is the force that causes the body to move (not rotate).

What is the difference between torque and couple?

Torque is produced due to a single force. ... The turning effect produced is called torque or moment of force. Couple is produced due to two forces that are equal in magnitude but opposite in direction( unlike parallel forces) and do not have the same line of action.eg a double arm spanner or a steering wheel etc.

What is definition of torsion?

In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. ... In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius.

What is an example of torsion?

Twisting a simple piece of blackboard chalk between ones fingers until it snaps is an example of a torsional force in action. A common example of torsion in engineering is when a transmission drive shaft (such as in an automobile) receives a turning force from its power source (the engine).

What is J in torsion formula?

General torsion equation

J = polar moment of inertia or polar second moment of area about shaft axis, [m⁴, in⁴] τ = shear stress at outer fibre, [Pa, psi] r = radius of the shaft, [m, in]

Is torque a force?

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.

Why is torque called moment?

The direction of the force is important because the resulting motion of the object is in the same direction as the force. The product of the force and the perpendicular distance to the center of gravity for an unconfined object, or to the pivot for a confined object, is^M called the torque or the moment.

Is a moment a force?

A moment is due to a force not having an equal and opposite force directly along it's line of action. ... It is defined as the product of the force (F) and the moment arm (d). The moment arm or lever arm is the perpendicular distance between the line of action of the force and the center of moments.

What is the torque of a couple?

Couples. A couple is two equal forces which act in opposite directs on an object but not through the same point so they produce a turning effect. The moment (or torque) of a couple is calculated by multiplying the size of one of the force (F) by the perpendicular distance between the two forces (s).

What is restoring couple?

When the two equal or opposite forces are exerted at the two ends of an object, it constitutes a couple. ... where the Angle of twist at the lower end of the wire is ∅, restoring couple is C∅, where C is the torsional rigidity of the wire, and I is the moment of inertia of the disc about the axis of the wire.

How do we calculate torque?

A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.
