The 3.10 kg 34.0-cm-diameter disk is spinning at 350 rpm, Ask an Expert

Academics

Q.If the mass of both weights is 250 gm, the first mass is located 30 north of east, the second mass is located 30 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

Q. The 3.10 kg, 34.0-cm-diameter disk is spinning at 350 rpm How much friction force must the brake apply to the rim to bring the disk to a halt in 2.20 s?
