At the instant under consideration, the cable attached to the cart of mass m1 is tangent to the circular path of the cart. If the upward speed of the cylinder of mass m2 is v2 = 3.0 m/s, determine the magnitude of the acceleration of m1 and the tension T in the cable. What would be the maximum speed of m2 for which m1 remains in contact with the surface? Use the values R = 7.75 m, m1 = 0.8 kg, m2 = 0.9 kg, and β = 31°

sorry to disappoint you but i’ve been using for years and never once have i seen a “live section.” i’m sorry and i hope this !

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.
