i worked it out and i don't believe it works because the inertia is greater than the first situation. The value should be lower because the mass increases as it approaches 1.9. So when you rotate it from the right side, it should be a lot easier to rotate the object and thus, a lesser value...
Homework Statement
A thin rod is exactly 1.9 meters long. The density in this rod varies in a peculiar manner. If we call the left-hand end of the rod x=0 and the right-hand end of the rod x=L , then the linear density can be expressed in units of kilograms per meter as...
yea i wasn't too sure of which limit to use... so I am going to guess the limit is going to be based on power transmission? If so then the new set of limits would be:
34 gauge: 0.056 A
32 gauge: 0.091 A
30 gauge: 0.142 A
Unless someone has another source for these numbers...
The soft iron soulds good... I'll see what i can find. What I'll be doing today is actually drawing out the motor design using AutoCAD so ill post the basic design of the motor, and then I can adjust accordingly to what needs are to be met. Ill post dimensions.
\frac {\mu I\ }{2R} Is the...
Bob S :
- I have planned out my geometry, It will be a 9 coil stator with a 12 magnet rotor.
- I also plan to use Hall sensors in my motor
- DO you think you can elaborate a little bit on the lamination and eddy currents, do you mean the iron will need a laminate coating?

I am trying to produce a magnetic field with a flux density of 1 Tesla through a solenoid with an iron core and I am having trouble crunching the numbers. I may also be doing the wrong computations. I am not too sure of the permeability of the iron core, I've seen different values, one being the...
sry, I forget how specific you sometimes need to get with problems. Using the inertia of a cylinder, the equation is I = 1/2 * M(R^2) . Now that is for just the cylinder. What I am trying to figure out is if the mass of the load will sneak itself into the equation or will it be an outside factor...
Think of a cart on wheels... the cart has some given mass and I want to know what's the relationship between the mass of the cart and the inertia of the wheels. I know the weight is dstributed evenly to the wheels, but i get stuck when it comes to the inertia, wether weight affects it or not
How is rotational inertia effected by weight if at all? I am designing wheels and I'm considering the load placed on these wheels. I am not sure if the mass of the load should be incorperated into the inertia at all. Thanks!
