An R-134a thermal expansion valve system contains the proper refrigerant charge. During a system perfor- mance test, the low-side gauge reading is 40 psig and the high-side gauge reading is 140 psig with an ambi- ent air temperature of 878F (30.558C). Which of the fol- lowing is the most likely cause of these results

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.)
