The gauge pressure of a pneumatic cylinder reads 40 lb/in^2 when the volume is 15 in^3. The cylinder is compressed until the gauge reads 50 lb/in^2. Assume standard atmospheric pressure (14.7 psi). Sketch and label all known and unknown values in your Engineering Notebook

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
