Q. If the mass of both weights is 225 gm, the first mass is located 20 north of east, the second mass is located 20 south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure? Assume the transducer has been properly zeroed so that V = 0 when F3=0.
