In the following figure radii `r_1` and `r_2` are 10 cm and 20 cm respectively. If the moment of inertia of the wheel is 1500 kg `m^2`, then determine its angular acceleration.

Text Solution

Verified by Experts

Angular acceleration `alpha=(tau)/I=((5+10)r_(2)-15r_(1))/I`
`=(15(20-10)xx10^(-2))/1500`
`=10^(-3)"rad"s^(-2)`

Figure shows two cylinders of radii r_1 and r_2 having moments of inertia I_1 and I_2 about their respective axes. Initially the cylinders rotate about their axes with angular speed omega_1 and omega_2 as shown in the figure. The cylinders are moved closer to touch each other keeping the axes parallel. The cylinders first slip over each other at the contact but the slipping finally ceases due to the friction between them. Find the angular speeds of the cylinders after the slipping ceases.
