Torque of Tray Tilter

I was wondering if anyone knew how to calculate the maximum weight that a tilter with 1 V5 motor could push. Would the angle and the lengths of the two arms affect the torque? Any help would be appreciated!

Both the angle and the lengths of the two arms affects the torque. As the length of the tilting arm approaches zero, the torque of the system approaches infinity.

Think of the linkage as a gear ratio connecting the driven gear and the tray angle. If for every degree that the tray angle tilts the driven gear turns 5 degrees, there’s a 1:5 torque ratio provided by the linkage. This ratio isn’t completely linear but it’s close enough for stuff like this. Therefore to maximize torque you’ll want to build your tilter to have as large of a range of motion as possible, and play with your linkage until when the first bar is as far back as it can go, the tray is at resting angle, and when the tray is 95 degrees (a little extra is safe), the first arm is all the way forward.
