(a) Design a band-pass filter consisting of an RC high-pass filter with a cutoff frequency of 125 Hz and an RC low-pass filter with a cutoff frequency of 500 Hz. "Carefully select the R and C of each filter so that one filter does not load the other, changing the cutoff frequencies. Make one" of the two resistors equal to 1.5 kΩ. (b) Sketch and label the circuit. (c) Calculate the gain of the band-pass filter at 125 Hz, 250 Hz, and 500 Hz. (d) Comment on your results in c.

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.
