A device of 200 N in weight is to be isolated from a panel that vibrates at frequencies in the range 10 Hz to 20 Hz. An isolator is designed to isolate at least 80% of the force being transmitted from the panel vibration to the device. Assume the selected isolator has zero damping. Determine: (a) The minimal value of static deflection required for the isolator to achieve the desired isolation. (b) The maximum value of static deflection required for the isolator to achieve the desired isolation.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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)?
