Derive the equation of motion of the mass m shown in Fig. 3.66 when the pressure in the cylinder fluctuates sinusoidally. The two springs with stiffnesses k1 are initially under a tension of T0. and the coefficient of friction between the mass and the contacting surfaces is µ.
The pipe flow experiment deals with fluid flow through a non-circular cross-section “pipe”. Please explain, using supporting equations, how you would calculate the pressure loss during fluid flow between two points along the pipe.
An electric immersion heater, 10 mm in diameter and 300 mm long, is rated at 550 W. If the heater is horizon- tally positioned in a large tank of water at 20°C, estimate its surface temperature. Estimate the surface temperature if the heater is ac..
a pump accepts liquid water at 60 acircdegf and 14 psia and compresses it to a pressure of 100 psia. the pump has a
Using the data shown in Figures 6.14 (at 25oC) and 6.21, combine both curves onto one plot, being careful to correctly plot the modulus, yield strength, tensile (ultimate) strength, and ductility. Discuss how the modulus, yield strength, and ductilit..
A 4 cylinder 1.6 liter SI engine has a compression ratio of 10, connecting rod length of 16.8cm, and a crank offset of 4.5 cm. The engine is operating at 3000 RPM and wide open throttle. The exhaust pressure is 100 kPa. The intake valve closes at 20 ..
a straight fin of uniform cross section is fabricated from a material of thermal conductivity 50 wmk thickness w6mm and
Find the relative velocity of the systems.
A lathe can be modelled as an electric motor mounted on a steel table. The table plus the motor has a mass of 50 kg. The rotating parts of the lathe have a mass of 5 kg at a distance 0.1 m from its center. The damping ratio is 0.06 and the natural fr..
The beauty of a bicycle wheel design is that the spokes (narrow cylindrical wires connecting the wheel center to the perimeter) are loaded in tension, despite the compressive force exerted via the bicyclist's weight. Consider a stainless steel spoke ..
Assuming that the orbit of the moon is a circle of radius 384 A? 103 km, determine the speed of the moon relative to the earth.
1. A piston-cylinder assembly contains 0.1 lb of propane. The propane expands from an initial state where p1 5 60 lbf/in.2 and T1 5 30°F to a final state where p2 5 10 lbf/in.2 During the process, the pressure and specific volume are related by py2 5..
a piston-cylinder device with a piston surface area of 0.1m2 is initially filled with 0.05m3 of air at the local
