ANSWERS

1) False - it stands for "American National Standards Institute "  2) False - Absolute Pressure = Atmospheric Pressure plus Gauge Pressure  3) True  4) False - The purpose of the Ball Bearing is to reduce rotational friction and support radial and axial loads  5) a) 9.29  6) True  7) False - Pneumatic Cylinders use a compressed gas - typically compressed air  8) False - A solenoid is activated by electrical energy  9) False - Resonance is the tendency of a system to oscillate with greater amplitude  at various frequencies  10) False - Seismometers measure motions of the ground such as seismic waves generated by earthquakes, etc
