In an earlier edition, the writer asked the following question about Fig. 5.1: "Which of the three graphs is a more effective presentation?" Why was this a dumb question?

#### What is the ratio of the strain energy u1 in the tube

A thin-walled circular tube and a solid circular bar of the same material, the same cross-sectional area, and the same length are subjected to torsion. What is the ratio of

#### The ratio of mass flow rates of warm to cold air streams

In air-conditioning systems, streams of cold and warm air are mixed to get air with the right temperature. Consider a mixing chamber into which cold air enters at 8C and 100 k

#### Determine temperature and relative humidity at duct inlet

A fan within an insulated duct delivers moist air at the duct exit at 22°C, 60% relative humidity, and a volumetric flow rate of 0.5 m3/s. At steady state, the power input t

#### Estimate the ratio of impact energy

For the tensile impact bar shown in Figure P7.20, estimate the ratio of impact energy that can be absorbed with and without the notch (which reduces the diameter to 24 mm) A

#### Properties enthalpy and entropy are deriven from heat

In thermodynamics, path functions such as heat or work are dependent on path process, point functions are not. Properties enthalpy and entropy are deriven from heat and work r

#### Determine the coefficient of restitution e and the velocity

The 500-lb ram of a pile drive falls 4 ft from rest and strikes the top of an 800 lb pile embedded 3 ft in the ground. Immediately after impact the ram is seen to have no velo

#### Describe the criteria a bolted joint designer must consider

Name the principal modes of failure of both tensile and shear joints? Describe or list the criteria a bolted joint designer must consider when selecting bolt size and materi

#### Potential energy effects and modeling the air as ideal gas

Refrigerant 134a at a flow rate of 0.5 lb/s enters a heat exchanger in a refrigeration system operating at steady state as saturated liquid at 20 degrees Fahrenheit at a press
