The cross section of the bar shown is symmetric about either the x or y axis.
(a) Determine d so that the origin of the coordinate system, point O, is positioned at the centroid of the area.
(b) Determine the area moment of inertia about the x axis.
(c) Determine the area moment of inertia about the y axis.
Determine the amplitude of motion of the machine, the phase shift of the motion (with respect to a zero phase exciting force), the transmissibility ratio.
Air enters a non-ideal gas turbine at T1 = 2290°F, P1 = 196 psia and exits at T2 = 1200°F, P2 = 14 psia. (a) Assuming constant specific heats evaluated at 1000F, find the turbine efficiency using the Air Tables.
A certain thermocouple has a time constant of 1.2 s. Design a compensation network like that shown in Fig. 8.34 having a steady-state attenuation factor of 8. Select the value of the resistance so that the capacitor has an even multiple value.
Water flows downward through a vertical smooth pipe. When the flowrate is 0.5 ft3 /s, there is no change in pressure along the pipe. Determine the diameter of the pipe.
Application: Loop antenna. A transmitter uses a Hertzian dipole, 0.02A long. Because of changes in design, it becomes necessary to replace the Hertzian dipole by an equivalent loop antenna, keeping the current in the loop the same as the current i..
Assume zero stress in the stay on completion of fitting. when the temperature falls to -10 degrees centigrade, the gap between the walls is reduced by 0.5mm. Determine the stress in the 'stay' at this temperature.
Gold Brick you win the lottery and decide to impress your friends by exhibiting a million-dollar cube of gold. At the time, gold is selling for $426.60 per troy ounce, and 1.0000 troy ounces equals 31.1035 g. How tall would your million-dollar cub..
Find the equation of the tangent line at (3, 4) by finding the equation of the line passing through (3, 4) which is perpendicular to the (radius) line segment whose end points are (0, 0) and (3, 4)
A voltage signal consists of a pure sine wave of amplitude 10.0 V at 180 Hz. This signal is sampled digitally at a sampling frequency of 200 Hz. 128 data points are taken.
A single model manual assembly line produces a product whose work content time = 47.8 min. The line has 24 workstations with a manning level = 1.25
Find (a) the angular acceleration, (b) the time taken, (c) the work done, (d) the maximum power developed, (e) the distance travelled by a point on the rim of the flywheel.
Show that the motion of the system is stable provided that r c/m.
