Oh, isn't that a lovely question! To find the angle of twist per meter length, we can use the formula for angle of twist in a hollow shaft. We'll need to calculate the polar second moment of area, then apply the formula using the given values for shear stress and modulus of rigidity. Remember, take your time with the calculations and enjoy the process of solving this delightful problem!

Oh, honey, you want the angle of twist per meter of that shaft? Well, buckle up! First, calculate the shear stress using the formula Ο = T*r/J, where T is the torque, r is the radius, and J is the polar moment of inertia. Then, use the formula Ο = TL/GJ, where L is the length of the shaft, G is the modulus of rigidity, and J is the polar moment of inertia. Plug in those values and you'll have your angle of twist per meter. Easy peasy lemon squeezy!

Q: Find the angle of twist per metre length of a hollow shaft of 100 mm external diameter and 60 mm internal diameter if the shear stress is not to exceed 35 MPa. Take modulus of rigidity G 85 GPa.?

Answer

what we now call just the "slope" was once called the "modulus of slope", the word "modulus" being used in its sense of "number used to measure" (as in "Young's modulus").

6.3246 (rounded)

32 is the modulus. Modulus means the total number of counts. Maximum count of a five stage binary counter would be 11111 or 2^4 + 2^3+2^2+2^1+2^0 = 31 plus the count of zero = 32.

If you have a stress strain curve that is non-linear the secant modulus is the slope of a straight line connecting the zero strain point to the final strain point of interest

there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on

modulus of elasticity = 15 Msi; poisson ratio = 0.3 modulus of rigidity = E/ ((2(1 + poisson)) = 5.8 Msi

G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus

The modulus of rigidity of a wire is a measure of its resistance to shearing deformation. It is typically represented by the symbol G and is expressed in units of pascals (Pa). The specific value of the modulus of rigidity for a given wire will depend on its material composition and properties.

It is around 40 GPa.

shearing stress to shearing strain

about 70 to 80 GPa

It is defined as ratio of the product of modulus of rigidity and polar moment of inertia to the length of the shaft. Torsional Rigidity is caluclated as: Torsional Rigidity= C J/l

It is the ratio of shear stress to shear strain.
