I have a question. I am working on a small project for class. We have locking Geneva mechanism that turns a table made of cast iron 72* in .5 seconds. The table mass is calculated to be 7300 kg (D=1.25m, h=.350m).(adsbygoogle = window.adsbygoogle || []).push({});

Based on the 72* in .5 seconds, I calculated alpha to be 10.08 rad/s^2. Using I=m*r^2/2, I calculated I to be 612.3. Torque (Nm)=alpha*I=6172N*m.

For power, I used the equation P (Kw) = (Torque*2*pi*rpm)/60,000. And I used alpha*t to solve for the RPM, which ended up being 5.04 rad/s = 2888 rpm. My power required ends up being 1867Kw which seems ridiculously high. Am I calculating this correctly?

Let me know of any other info you need.
