How to calculate the force required? Design of Rack and Pinion
(OP)
Hello everyone. This is Govardhanan. I am still a student, when mechanics is considered, so please tolerate my simple questions and pls do help me out.
I am trying to dispense some food from the container using a rack and a pinion, but was not successful in that, as the stepper motor I use doesnt give enough torque. So I need to know the torque I am supposed to generate to dispense the food. But I am not sure how to measure the force required to dispense the food. Please help me out in designing this. Thanks a ton in advance.
I have attached the rough explanation drawing and an image of what I have done already.

Thanks for your response man. I will try doing this. Btw, I am trying to design a gear mechanism to dispense this, with a stepper motor of 11.5 kgcm holding torque at the back. Can you help me with power transmissions in gears? As you can see in the attached image, it was a failure when we directly coupled the rack with the motor shaft's pinion.
