What is torque in strength of materials?

What is torque in strength of materials?

Torque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section.

Which should be able resist more torque a solid bar or hollow bar of the same material and cross sectional area explain?

The stiffness of the hollow shaft is more than the same weight solid shaft. The strength of the hollow shaft is more than the same weight solid shaft. Hollow shafts have a more polar moment of inertia, which enables them to transmit more torque than solid shafts.

Is hollow or solid shaft stronger?

A hollow shaft is found to be stronger than a solid shaft made of the same size and material. Reason: The torque required to produce a given twist in a hollow cylinder is greater than that required to twist a solid cylinder of the same size and material.

Which shaft has more strength?

A hollow shaft has greater strength and stiffness than solid shaft of equal weight.

Is torsion and torque the same?

Torque and torsion are both related to turning effects experienced by a 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.

Which is stronger solid steel rod or hollow steel pipe?

And, it’s a common myth that a solid rod bends easier than a hollow tube of the same material. Fact is, given the same material, a solid rod is stronger in all respects than a hollow tube of the same material. solid and weigh less.

Why are hollow shafts better than solid shafts?

the stiffness of hollow shaft is less than that of solid shaft. the strength of hollow shaft is more than that of solid shaft.

Which is stronger pipe or rod?

And, it’s a common myth that a solid rod bends easier than a hollow tube of the same material. Fact is, given the same material, a solid rod is stronger in all respects than a hollow tube of the same material.

Why hollow tubes are stronger?

A hollow tube of the same mass as a rod is bigger. When the mass is further of inertial axis, it resists bending more. So the tube will be harder to bend.

Is hollow pipe stronger than solid?

Fact is, given the same material, a solid rod is stronger in all respects than a hollow tube of the same material. tube can have greater strength than the smaller O.D. solid and weigh less.

What is torsional stiffness of shaft?

where I p = π D 4/32 is the polar moment of inertia of a circular cross section. Thus, combining Equations (6.8) and (6.14) we have. Thus, the torque required for unit twist, i.e., T (θ) is called the torsional stiffness. From the above relation, The quantity is known as torsional rigidity and is represented …
