Question

Determine the shear strain on a tubular shaft. The tubular circular shaft has a length L, inner diameter d1, outer diameter d2, and shear modulus G. What is the shear strain?

Answer 1

The shear strain on a tubular shaft can be determined using the formula (d2 - d1) / (2L). The shear modulus does not need to be considered for calculating the shear strain.

Step-by-step explanation:

The shear strain on a tubular shaft can be determined using the formula:

Shear strain = (d2 - d1) / (2L)

where d1 and d2 are the inner and outer diameters of the shaft respectively, and L is the length of the shaft. The shear modulus does not need to be considered for calculating the shear strain.

For example, if the inner diameter of the shaft (d1) is 4 cm, the outer diameter of the shaft (d2) is 6 cm, and the length of the shaft (L) is 10 cm, then the shear strain would be:

Shear strain = (6 - 4) / (2 * 10) = 0.1 cm/cm = 10%
