Bourdon-type pressure gauges are used in thousands of applications. A deadweight tester is a device that is used to calibrate pressure gauges. Investigate the operation of a deadweight pressure tester. Write a brief report to discuss your findings.

We have used an experimental setup similar to Example 10.1 to determine the value of a spring constant. The deflection caused by the corresponding weights are given in the accompanying table. What is the value of the spring constant? Weight (lb) The Deflection of the Spring (in.) 5.0 0.48 10.0 1.00 15.0 1.90 20.0 2.95

Former basketball player Shaquille ONeal weighs approximately 335 lb and wears a size 23 shoe. Estimate the pressure he exerts on a floor. What pressure would he exert if his shoe size were 13? State all your assumptions, and show how you arrived at a reasonable solution.

SAE 30 oil is contained in a cylinder with inside diameter of 1 in. and length of 1 ft. What is the pressure required to decrease the volume of the oil by 2%?

Calculate the R-value for the following materials: a. 4 in. thick brick b. 10 cm thick brick c. 12 in. thick concrete slab d. 20 cm thick concrete slab e. 1 cm thick human fat layer
