Question

If the mass of both weights is 150 gm, the first mass is located 25° north of east, the second mass is located 25° south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure (volts)? Assume the transducer has been properly zeroed so that V = 0 when F3 = 0.

Answer 1

Answer:

voltage is 1.38 V

Explanation:

given data

weights = 150 gm = 0.150 kg

sensitivity = 0.5 volts/Newton

to find out

large a voltage

solution

we know here in by symmetry so here in x axis

F3 will be

F3 = 2mgcos(20)

F3 = 2(0.150)(9.8)cos20

F3 = 2.76 N

so volatge is

voltage = 2.76×sensitivity

voltage = 2.76×0.5

voltage = 1.38

so voltage is 1.38 V
