Question

yNotes 0/1 points 1 Previous Answers W86 8.065.E. Two masses are suspended from a pulley as shown in the figure below (the Atwood machine). The pulley itself has a mass of 0.30 kg, a radius of 0.15 m, and a constant torque of 0.35 m. N due to the friction between the rotating pulley and its axle. what is the magnitude of the acceleration of the suspended masses if m 0.60 kg and m2 1.00 kg? (Neglect the mas string.) 8.19 x m/s? of the Ti T2 T, T2 9 18 mas et's

Answer 1

let the acceleration of masses is m

frictional force = 0.35/0.15 N

Now, for the net acceleration

net acceleration = net force/total effective mass

a = (1 * 9.8 - 0.60 * 9.8 - 0.35/.15)/(1 + 0.60 + 0.50 * 0.30 * 0.15^2/0.15^2)

a = 0.91 m/s^2

the acceleration of each mass is 0.91 m/s^2
