Torsion of Solid and Hollow Shaft Calculator to calculate shear stress, angle of twist and polar moment of inertia parameters of a shaft which is under torsion. The calculator is only valid for sizing of solid/hollow circular shafts.
This calculator works out the Torsion in a Shaft, using the moment, length, diameter and material type.
28 lis 2012 · I am trying to determine the maximum torque that this shaft can take before breaking. Imagine that the one end of the rod is fixed in a vice, and I'm applying torque with a 1 foot breaker bar, I want to calculate the max torque that the rod can withstand (I'm assuming this is fairly basic).
Maximum moment in a circular shaft can be expressed as: T max = τ max J / R (2) where. T max = maximum twisting torque (Nm, lbf ft) τ max = maximum shear stress (Pa, lbf /ft2) R = radius of shaft (m, ft) Combining (2) and (3) for a solid shaft. T max = (π / 16) τ max D3 (2b) Combining (2) and (3b) for a hollow shaft.
How to Use the Torsion Calculator. Enter the following values into the calculator: Length (L): The length of the object experiencing torsion in meters. Radius (r): The radius of the object in meters. Shear Modulus (G): The material’s shear modulus in Pascals. Torque (T): The applied torque in Newton-meters.
This page includes various formulas which allow calculation of the angles of twist and the resulting maximums stresses. The equations are based on the following assumptions 1) The bar is straight and of uniform section 2) The material of the bar is has uniform properties.
In most steel-framed structures, beams are subject only to bending and not to torsion but situations do arise where torsional effects are significant, typically where the demands of practical construction result in eccentrically applied loads.
