Roll of film |
2021-11-20 |
|
From Brian:
Trying to create a formula to calculate the build up on a roll of film is calculated. Except instead of of a roll, it's essentially a rectangle with two semicircles on each at the end.
Example: I start with a 6" diameter core on each side, and I start winding .005"
thick film on the core. The distance between the center of those cores, length of the inner rectangle is 7.125.
If I continue to do this for a total length of film of 3000 feet, what will the
roll length and width be.
So what I need is the formula to perform this type of calculation.
Can you help me? I want to be able to plug the formula in a spread sheet and to be able to input a core diameter, a film thickness and a total length and the length between the center of the two cores(which is the inner rectangle's length I'm assuming).
Thanks

|
From Louie:
I teach carpentry on an Indian reservation.
My students want to make an 18 inch drum frame.
They want to have 8 sides or an octagon shape to the drum frame.
What angle I have to set my miter saw to cut the angles to fit the octagon together.
I want to use this formula by changing the diameter of the frame.

Volume of liquid remaining in a tilted cylinder |
2016-11-08 |
|
From Brian:
I am trying to determine the amount of a liquid remaining in a 55 gallon drum when it is tilted at 45 degrees and the liquid level is low enough so that the liquid does not completely cover the bottom of the drum.
Your help is greatly appreciated.
