Question

A mass hung on a string that is wrapped around an axle on a wheel produces a tension in the string of 1.65 N. The axle has a radius of 0.085 m. The wheel has a mass of 4.000 kg and a radius of 0.245 m. (Enter your answers to two significant figures.) What is the magnitude of the torque produced by the tension on the axle? r = BE) N m The mass has an acceleration of 0.545 m/s2. What is the magnitude of the angular acceleration a of the system? a = 5SL/J rad/s^2 Additional Materials Rotational Motion

Explanation / Answer

a) =T.r1

=(1.65N)(0.085m)

= 0.14025 N-m

b) =a/r

=(0.545m/s2)/(0.245m)

= 2.23 rad/s^2
