I am working on a school project that requires me to build a machine. I have designed the machine but I am stuck at torque calculation. The problem goes like this, the machine supposes to rotate a stack of trays (5 trays stacking up vertically) at a constant speed.
Below is the information:
Mass of each tray: 8 kg
Tray Radius: 0.3 m
Moment of inertia of each tray: 0.333 kg m^2
Let's just say the friction is very small and can be neglected. The rotational speed should reach 1200 rev/min in 5 seconds. How do I calculate the torque required to rotate the stack of trays?
Any help would be appreciated!
