Hi, all! I am looking for some assistance on designing a machine. I have to admit, I am just a Mechanical Designer/Draftsman, and need some help determining the right motor to use. Here is the setup: -I have a 60" diameter table. It is 0.25" thick. I am using general steel density to spec it's weight to about 185lbs. This weight is calculated with slots cut out of table, reducing overall weight. -On top of the table, there will be a load of 3,750lbs. This is a coil with an ID of 35", and an OD of 57". -All in all, there is 3,935lbs atop the table. -I have motors with a 1" shaft diameter. My question is, how much torque will be required to rotate the table top (with load) at a speed of around 1-2 RPM's? I am slightly confused on the formulas, so any help is greatly appreciated! Thanks! Also, see the sketch I did for descriptions in detail!
