Calculation of Strength
For a tube of silicone rubber with a tensile strength of 10 MPa and a 8 mm outer diameter and 2 mm thick walls. The maximum pressure may be calculated as follows:
- Outer diameter = 0.008
- Wall thickness = 0.002
- Tensile strength = 10 * 1000000
- Pressure burst = (Tensile strength * Wall thickness * 2 / (10 * Outer diameter) ) * 10
Gives burst pressure of 5 MPa.
Using a safety factor:
- Pressure max = (Tensile strength * Wall thickness * 2 / (10 * Outer diameter) ) * 10 / Safety_factor

“And yours,” said the P.B.”

“Curse of the orchard,
Blemish on the land’s fair countenance,
I have grown strong for strength denied, for struggle
In hostile woods. I keep alive by being the troublesome,
Indestructible
Stinkweed of truth.”
—Naomi Long Madgett (b. 1923)
