Okay I hope i can get some quick replies , its urgent i have a science project coming and what i want to do is rotate a cylinder using a d.c motor its a relatively small cylinder radius = 4 cm length around = 15 cm mass will be around 200-300 grams now i can't figure out how can a small d.c motor rotate this ? I have an attached file showing the schematic or rather what i want to make happen. please help me with what to do , and how can i make it happen. do i use two motors at both ends ? the rotations can be relatively small 50-60 rpm.
