Multiple choice.
a.
a piezometer is used to measure the:
select one:
1. gauge pressure in a static mass of liquid
2. pressure difference between two liquids
3. pressure if the flowing fluid is a gas
b. mark the correct statement:
select one:
1. local atmospheric pressure depends only upon the height of locality above mean sea level
2. a barometer reads the difference between local and standard atmospheric pressure

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
