The independent current source generates 0 current for t < 0 and a pulse 10te-5t for t > 0. a. Sketch the current waveform. b. At what instant of time is the current maximum? c. Express the voltage across the terminals of the 100 mH inductor, v, as a function of time. d. Sketch the voltage waveform. e. Is the voltage maximum when the current is maximum? f. At what instant of time does the voltage change polarity? g. Is there ever an instantaneous change in the voltage across the inductor? If so, at what time?

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.
