Question

For a tubular section with outside diameter 68 mm and inside diameter 49 mm. If the tube was subjected to a torque of 1996 Nm, what would be the maximum stress in the material, fts?

Answer 1

`\sigma = 44.286 N/mm2`

Step-by-step explanation:

given data:

outside diameter = 68 mm

inside diameter = 49 mm

torque = 1996 Nm =1996000 Nmm

we know that torque for tubular section is given as

`T = (\pi)/(16) \sigma (D_0^4- D_i^4)/(D_0)`

Plugging all value to get required value of maximum stress
`\sigma`

`1996000 = (\pi)/(16) \sigma (68^4 - 49^4)/(68)`

`\sigma = 44.286 N/mm2`
