Three masses are suspended vertically by a series of identical springs where mass #1 is at the top and mass #3 is at the bottom. If gg = 9.81 m/s2, mm1 = 2 km, mm2 = 3 kg, mm3 = 2.5 kg, and the spring coefficients, kk’ss = 10 kg/s2, solve for the displacements of each spring, xx1, xx2, and xx3. Use the program that you developed in problem #1 to solve for the displacements and compare to MATLAB’s backlash solver

answer:

make you upset

explanation:

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.

the negative terminal is know as Ground strap
