The stepped shaft shown must transmit 45 kW. Knowing that the allowable shearing stress in the shaft is 40 MPa and that the radius of the fillet is r = 6 mm, determine the smallest permissible speed of the shaft.
Use Modelsim and a VHDL test bench to simulate all the three models for a 4-to-1 multiplexer. Use basic gates for structural modeling. A tar VHDL library file is given for assistance.
A BCD code is being transmitted to a remote receiver. The bits are A3, A2, A1, and A0, with A3 as the MSB. Design this circuit to produce a HIGH for any error condition.
A solid sphere with a radius of 75 mm rolls (without slipping) down an inclined plane that is 5 m long. What is the angular velocity of the sphere at the bottom of the plane if it requires 10 seconds for it to reach the bottom
(a) GivenX=(00111)2 and Y=(00110)2 , compute the carrybits using the equations for a CLA. How many time units would youneed to compute all the carry bits and why (b). Compute all the sum bits usingthe aforementioned carry bits.
The 741 op amp is usually modeled on specification sheets as a voltage amplifier having the following parameters: Rin = 1 M, Av = 100,000, and Rout = 100 Using this information, develop equivalent circuits for the 741 as a current amplifier
Design a multi-stage audio amplifier for delivering an average power of 400 mW to a 16 Ohm speaker from a microphone that produces a 10 mV peak sinusoidal signal and has a source resistance of 1 kW. Use standard NPN QN2222 for your design.
1. The stress at a point has σx = 13 ksi (T), σy = 18 ksi (T) and τxy = +6 ksi. (3 pts) Determine the principal stresses for the plane stress problem.Calculate the maximum shear stress. Show the results on the diagram below.
An internally compensated op amp is specified to have an open-loop gain of 106dB and a unity-gain bandwidth of 3MHz. Find fb and the open-loop gain in dB at fb.
What is the rate at which the entropy of the low-temperature reservoir is changing. What is the rate at which the work production is changing the entropy of the engine surroundings
Repeat for a nonideal antisymmetric hybrid coupler. Assume that the couplers are matched at all ports.
Three point charges are positioned in the x-y plane as follows: 5 nC at y = 5 cm, -10 nC at y = -5 cm, and 15 nC at x = -5 cm. Find the required x-y coordinates of a 20-nC fourth charge that will produce a zero electric field at the origin.
Modulating Radio Frequency Carriers to Carry Digital Data, Digital radio transmission requires the use of a carrier wave which is modulated by the digital data.
