A tow truck applies forces F1 and F2 to the bumper of an automobile where F1 is horizontal. Determine the magnitude of F2 that will provide a vertical resultant force, and determine the magnitude of this resultant.
A mass "m = 2 kg" is connected to a spring with spring constant "k= 5 N/m " on a frictionless table oscillation only in 1-D (x direction) . The equation of motion for the mass is given by the equation m (d^2 x(t)/ dt^2) = -kx(t) .
If we wish to design a communication system which carries voice securely, we need to ensure that others cannot tap into the conversation. In digital transmissions, we can do this by encryption.
Design a simple BJT amplifier circuit for receiving the over-the-air HDTV signals. The circuit should have a voltage gain of 10-100, assuming your signal source (antenna) is connected to amp through a cable with an impedance of 75
The maximum radius a falling liquid drop can have without breaking apart is given by the equation: R = sqrt((sigma/gp)) where sigma is the liquid surface tension, g is the acceleration due to gravity, and p is the density of the liquid.
a. Calculate the optimum refractive index of a single layer thin film antireflection coating for the silicon air interface at this wavelength. b. Calculate the optimum thickness of the layer.
Determine the relationship between the steady-state error to a ramp input and the gain K and system parameter b. For what values of K and b can we guarantee that the magnitude of the steady-state error to a ramp input
Devise a detailed algorithm for a ring with p nodes so that each node would atttain the final sum of original node values. Determine the worst case communication steps for the algorithm.
What is the fundamental frequency of the spectrum of the square wave? What is the magnitude of the fundamental frequency component of the spectrum of the square wave?
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
The air feels humid. No air is coming from the registers. The air handler is in the attic. An examination of the condensing unit shows that the suction line has ice all the way back to the compressor. The compressoris still running.
A 10m diameter cylindrical tank is emptied by a constant outflow of 1 m3 /min. A two position controller is used to open and close a fill valve with an open flow of 3 m3 /min. For level control the neutral zone is 1m and the setpoint is 10m.
In a balanced three-phase wye-wye system, the load impedance is 10 +j1 Ohms. The source has phase sequence abc and the line voltage Vab = 220 Vrms /30°. The load voltage is VAN = 120 Vrms /0°.
