2018年10月31日 · The elastic modulus can be determined from the shear modulus if the Poisson ratio is known. In lieu of data, a value of 0.3 should be adequate. To get the given answer treating it as a cantilever, I need the elastic modulus to be 3/5 of the given shear modulus.

2013年4月25日 · Young's modulus represents the ratio of tensile stress to tensile strain, and the strain is non-dimensional. Similarly, the shear modulus represents the ratio of shear stress to shear strain. Young's modulus is related to shear modulus by a parameter known as Poisson's ration. The bulk modulus is also related to Young's and the shear moduli.

2017年10月6日 · Fluids have zero shear modulus, so fluid flow can be driven by an arbitrarily small shear stress. In this way, the shear modulus (or lack thereof) does define fluids, and the flow of fluids is indeed "related" to the shear modulus. But the question is vague. The bulk compressibility also characterizes the mechanical response of fluids, of course.

2016年9月12日 · It is with finding material properties. I never thought about angle of twist for a rotor shaft. I don't really know what acceptable margins of this are. I was trying to find a maximum shear stress of various types of steel but could only find a shear modulus. To use the shear modulus you need to know the angle of twist (I think).

2012年1月7日 · EDIT: I just caught up with post #3. Your 19,700 isn't the shear modulus, it also has some conversion factors from degrees to radians, and probably a factor of 16 or 32 because you are using diameters not radii.

A circular shaft (radius r=20mm ) with shear modulus G=0.8*105MPa and length l=5m is subjected to a pair of forces F acting on a circular lever of radius R=200 mm .Given the allowable shear stress τallow =150MPa, determine the allowed maximum value of F and the corresponding angle of twist.

A stepped steel shaft, ABC (shear modulus, G = 75 GPa; polar moment of inertia of each shaft section, J AB = 1.5708E-8 m 4 and J BC = 9.8175E-10 m 4) is subjected to the two torques, T B and T C. The torques T B = 7 N·m and T C = 4 N·m are applied at B and C in the directions shown. Find the magnitude of the angle of twist (degrees) of ...
