(Is a 14 or 4.88 ? ) A dual wheel having a load per tire of 9,000 lb, 120 psi pressure, and a 14-inch center to center wheel spacing is placed on an infinite space layer with a modulus of elasticity of 20,000 psi. Calculate the pavement displacement at a depth of 15 inches at the following radial distances from the centerline of one tire between the two tires: r = 0, 3, 6, 9, and 12 inches. Assume Poisson Ratio 0.5

A demonstration gyroscope wheel is constructed by removing the tire from a bicycle wheel 0.640 mm in diameter, wrapping lead wire around the rim, and taping it in place. The shaft projects 0.210 mm at each side of the wheel, and a woman holds the ends of the shaft in her hands. The mass of the system is 9.50 kgkg ; its entire mass may be assumed to be located at its rim. The shaft is horizontal, and the wheel...

A steel bicycle wheel (without the rubber tire) is rotating freely with an angular speed of 14.5 rad/s. The temperature of the wheel changes from -142 to 244 °C. No net external torque acts on the wheel, and the mass of the spokes is negligible. What is the angular speed of the wheel at the higher temperature?

A shovel with a 3.75-cy wheel loader will be used to load trucks from a quarry stockpile of processed aggregates having a maximum size of 3/8 inch. The haul distance will be negligible. The aggregate has a loose unit weight of 2950 lb/cy. Estimate the loader production in tons based on a 50-min hour efficiency factor. Use an aggressive cycle time and fill factor.

A 4-cy wheel loader will be used to load trucks from a quarry stockpile of uniform aggregates (1" and over in size). The haul distance will be negligible. The aggregate has a loose unite weight of 2,750 lb/cy. Estimate the loader production in tons based on a 50 min-hour efficiency factor. Use a conservative cycle time and fill factor.

An air-standard dual cycle has a compression ratio of 14. At the beginning of compression, p1 = 14.5 lbf/in.2, V1 = 0.5 ft3, and T1 = 50°F. The pressure doubles during the constant-volume heat addition process. For a maximum cycle temperature of 3500°R, determine: (a) the heat addition to the cycle, in Btu. (b) the net work of the cycle, in Btu. (c) the percent thermal efficiency. (d) the mean effective pressure, in lbf/in.2
