What is torsional rigidity and lateral rigidity?
Torsional rigidity: Ability to resist twist under the action of. an external torque. Lateral rigidity: Ability to resist deflection under the action.
What is a torsional rigidity?
The minimum torque required to deform an object by twisting through a unit dimension is known as torsional rigidity.
What do you understand by lateral rigidity?
Lateral rigidity is the force limit forces generated along its axis(es). With a rectangular solid, it can bend (curve) or deform the solid until its sides which are affected by the opposing forces becomes non parallel.
What is torsional rigidity find an expression for it?
where I p = π D 4/32 is the polar moment of inertia of a circular cross section. Thus, the torque required for unit twist, i.e., T (θ) is called the torsional stiffness. The quantity is known as torsional rigidity and is represented …
What is torsional factor?
The torsional rigidity measures the resistance of a bar to couples applied at the two ends. If M is the applied torque and θ is the angle of twist (per unit length of the bar), then the torsional rigidity is defined as C:=M/θ. Various symbols have been used to represent the factor C.
What is torsion and torsional rigidity?
The applied torque needed to produce a unit angle of twist in a circular elastic material; a measure of a body’s resistance to torsion. From: torsional rigidity in The Oxford Dictionary of Sports Science & Medicine »
What is torsional rigidity in mechanics of materials?
Torsional rigidity is the product of modulus of rigidity (G) & polar moment of inertia. Hence, torsional rigidity is also defined as the torque required to produce a unit radian angle of twist per unit length of the shaft.
What is flexural rigidity and torsional rigidity write their units?
Flexural rigidity of a plate has units of Pa·m3, i.e. one dimension of length less than the same property for the rod, as it refers to the moment per unit length per unit of curvature, and not the total moment. I is termed as moment of inertia. J is denoted as 2nd moment of inertia/polar moment of inertia.
What is torsional rigidity write their units?
The SI unit for unit for torsional rigidity is Nm². In solid mechanics, torsion is the twisting of an object due to applied torque. The SI unit is newtons per metre square because torsion is expressed in newtons per metre. It can also be expressed in pounds per square inch.
