Need confirmation for this question please: A pulley with Radius of 90mm and a mass moment of inertia 0.28$kgm^2$ about its central axis is subjected to a torque of 50Nm about this axis. What is angular acceleration of the pulley?
Soo, I did this: $\tau=I_o \cdot alpha$, therefore angular acceleration alpha= 50/0.28= 178.6rad/s^2??
Isn’t that number too high for a pulley please? What am I missing?
