A lawn mower component experiences critical static stresses of sx = 45,000 psi, sy = 25,000 psi, and txy = 15,000 psi. The component is made of 4130 normalized steel that has an ultimate strength of 97,000 psi and a yield strength of 63,300 psi. Determine the factor of safety based on predicting failure by the maximum-normalstress theory, the maximum-shear-stress theory, and the distortion energy theory

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
