For the circuit below, assume the components have the following values: Vs = 8 vpp, Cf = 200 nF, Rf = 10000 Ω, Ri = 500 Ω and ω = 1000 rads/sec. Answer the following questions for ω = 1000 rads/sec. Format all answers to two decimal points. 1) What is the feedback impedance in phasor notation? Zf = at an angle of o Ω. 2) What is the impedance of the input in phasor notation? Zi = at an angle of o Ω 3) What is the magnitude of the gain of this circuit in v/v? G = v/v. 4) What is the magnitude of the output voltage, vout? vout = vpp. 5) What is the cutoff frequency? What kind of filter is this? Are we operating in the passband? fc = Hz and this is a filter, so

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.

What is the chief metrological difference between measuring with a microscope and with an electronic comparator? a. the microscope is limited to small workpieces. a. the microscope is limited to small workpieces. c. the comparator can only examine one point on the workpiece. d. the microscope carries its own standard.

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
