Five metal strips, each 0.5 X 1.5-in. cross section, are bonded together to form the composite beam shown. The modulus of elasticity is 30 X 106 psi for the steel, 15 X 106 psi for the brass, and 10 X 106 psi for the aluminum. Knowing that the beam is bent about a horizontal axis by a couple of moment 12 kip.in., determine
(a) the maximum stress in each of the three metals,
(b) the radius of curvature of the composite beam.
The rectifier outputvoltage ripple factor must not exceed 5%. In your design, assumethe voltage variation during discharging period is linear and theoutput voltage ripple frequency is twice the source frequency.Assume the transformer to be ideal.
A certain op amp has an open-loop dc gain of A0OL = 200, 000 and an open-loop 3-dB bandwidth of fBOL = 5Hz. This op amp is used in a non-inverting amplifier having a closed-loop dc gain ofA0CL = 100. Determine the closed-loop break frequency fBCL.
Critical frequency for the input low pass network, and the output low pass network, estimate the values for Cbe, Cjc, Cbc, and Cje. Concider the resistance of the signal sourceRs to be equal to the 1 ohm resister in series with the source.
The parameters of an n-channel enhancement-mode MOSFER are VTN = 0.5V, k'n = 120μA/v2, and W/L = 4. What is the maximum value of λ and the minimum value of VA such that for VGs = 2V, ro ≥ 200kΩ?
What is the blocking probability of the system in (b) when the maximum number of users are available in the user pool?
purchase an inductor coil for a resonance circuit resonating at 1500 kHz; the operating bandwidth is 10 kHz. What is the quality factor Q of the coil
Mrs. Brooke owns a robot with an FSM brain. The robot walks from left to right along a paper type containing a sequence of 1's and 0's. On each clock cycle, the robot walks to the next bit.
There are three gates. Each gate can be opened or closed depending on the three logic inputs: (a, b, c). Gate open logic=1, gate close= logic 0. Design a logic circuit so that no adjacent gates or outputs (x, y, z) are open at the same time.
Questions 1. Describe what is meant by the voltage gain of an amplifier 2, What is the primary purpose of a coupling capacitor ub transistor amplifiers?
Create a function that transmits one byte to an HD44780 LCD controller using the following sequence. Allow one microsecond between each instruction. To clock in a byte: Set the E line low.
A CMOS output driver circuit on an IC is connected to an external transmission line. The NMOS and PMOS transistors have gate oxide thickness d = 2.0 nm and channel length L = 0.25 mum. The power rail is VDO = 1.0 V.
