Design both an inverting and a non-inverting amplifier with a gain of 15.b. an input signal has a maximum voltage of 100mv, what is the maximum magnitude of the source current in your designs? c. what is the effect on the output signal in both designs if the input signal has high impedance? (the input is a voltage source in series with a large resistor)

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.
