Can anyone explain why the moment of inertia for a tubular column in that textbook is like so? (take a look at the attachments). It should be (I = MR^2), as far as I know.
If I was required to select a water pump for either domestic use or industrial, what are the consideration that I should take care of while choosing?
How can I select a suitable pump according to height? What power should be implemented?
Anyway, a general question would be "What is a reference...
@Baluncore
I think this is a great analysis
This can be solved by supporting the horizontal shaft by equally-distant vertical pillars- using journal bearings, of course.
Should this be done also with the horizontal shaft, because i think this will be a bit complex in our case. And if it is...
Here is the application to be implemented. It is a solar tracker, and i need to choose the proper motors for it, and still confused how the vertical load will affect motor's torque- I'm talking about the vertical-shaft motor.
And as our friend @Baluncore here said,
Is it better done with a...
Can you please explain why the weight does not affect the whole operation of rotation.
Are you saying it is a matter of bearing drag? How to calculate it in this case? and what is its significance. Thank you.
I don't need to directly choose a motor, i need the formulas to calculate it.
The issue is that I'm confused between the vertical and horizontal load- i.e. in this case the load is vertical (weight) and the torque to rotate the gear is horizontal. How to combine these two forces in one...
If I'm to choose a motor to suit a vertical load (torque)-see the attached picture for more illustration-. What is the criteria should i follow?
After i have done the math for the weight of the object to be rotated, the torque to rotate the load is to be horizontal, and i only have the weight...
