**helical linear spring shear stress (τ) calculator** - step by step calculation, formula & solved example problem to find the shear stress of the helical linear spring in mechanical engineering. Spring constant K_{s}, load in Newton F, mean spring diameter D in mm & wire diameter d in mm are the key terms of this calculation.

For mechanical springs in mechanical engineering, the below mathematical formula is used to calculate the shear stress of the helical linear spring

The below step by step solved example problem may helpful for users to understand how the input values are being used in such calculations to calculate the shear stress (τ) of the helical mechanical spring.

**Example Problem**

The helical linear spring having the load F = 100 Newton, mean spring diameter D = 14 mm, wire diameter d = 10 mm & spring constant K_{s} = 1.35. What is the shear stress of it?

**Solution**

The given data

load in Newton F = 100 N

mean spring diameter D = 14 mm

wire diameter d = 10 mm

spring constant K_{s} = 1.35

__Step by step calculation__

Formula to find τ = K_{s}(8 x F x D/π x d^{3})

substitute the values in the above formula

= 1.35 x (8 x 100 x 14/π x 10^{3})

**τ = 4.80 Pa**
