Answer:
The stress in the rod is 39.11 psi.
Explanation:
The stress due to a pulling force is obtained dividing the pulling force by the the area of the cross section of the rod. The respective area for a cylinder is:
Replacing the diameter the area results:
Therefore the the stress results:
Unless cylinders are firmly secured on a special carrier intended for this purpose, regulators shall be removed and valve protection caps put in place before cylinders are moved. A suitable cylinder truck, chain, or other steadying device shall be used to keep cylinders from being knocked over while in use.

Explanation:
The measures that can be taken to control and prevent the formation of strss corrosion cracks are:
a) Selection and control of material
It deals with the selection of the best quality material that can resist the stress corrosion cracks to a high extent.
b) Control of stress
It is to control or reduce the intensity of the major stress that causes the stress corrosion cracks.
c) Control of the environment
It includes the prevention of the material from the corrosive environment by removing the component from the region or controlling the environment condition around the object.
The answer is increases because when something like that decreases it’s always decreasing that probly makes no sense Imao but it’s increases
