Would you at first thought think they are not as capable as male engineers? If they dressed like a secretary say, would that make you think they are any less capable?

This is maybe specific request. I need sketch of a figure with its dimension, that is to be made metal model of.
It has shape of a cone without its peek (cut of peek), and these are its specific dimension:

- base circle R=305 mm
- top circle R=278 mm
- distance between these two circles (the figure height) h=125 mm

I need something like a blue-print. That picture should be made in a way that, when drawn in metal, than cut off, scrolled and put together, form the shape I previos described.

thanks

If one newton is approximately 98 kg per metre would the answer be 9 newtons ?. If so why don't I fall through the floor of an average house designed for loads of only 4 newtons ???

I know that fluctuation will eliminate if using flywheel but is there a tendency that a big flywheel can be a big load for the engine when it's slow down?

But why is it the opposite in the experiment that i made? I think it has something to do with the rate of feeding the material into the jaw crusher. I don't think the power should be investigated but the energy. Because indeed, there is greater energy requirement to reduce a material into smaller size.

Can anyone comment about this? Or do you have other explanation?

I was wondering how to calculate the proper size for both resistance and wattage to bleed out a capacitor. The capacitor if for smoothing a DC motor and will be around 10,000 to 15,000 uf at 48 volts.

Ever since I moved in with my Grilfriend, she has kept our new batteries in the fridge. Who else out there does this and does it really extent the life of the battery?

I have an idea for an invention and I was wondering how I could go about making the product or who to speak to and how it all works? I know that I would need a patent but I don't even know where to start once I have discovered the idea.Can you help?

I need to construct a machine that will be able to climb a piece of string from one end of a classroom to another. (The string will be an an angle between 20 & 30 degrees) Each machine must have a switch, 9v battery, snap connector, and motor.

I have no idea where to start with this. Help?

Im trying to use 12 volt solar system to power around the house. I have a 12 volt battery and inverter. works well with CF lights. Now i found a AC/DC TV. But the math says it uses more power under dc than ac. DC specs are 12 volts and 16 watts. works out to 1.3 amps. AC is 120 volts and 35 watts. works out to .3 amps. watts divided by volts equals amps. So its better to just use AC power? I was going to run direct by battery but it looks like going thru the inverter would be better. Is this right? Is their that much difference? 1 amp. I guess internally it has to make ac and that is consuming more power? Man, i thought i was getting somewhere with a dc tv but really i'm losing by going DC. Is this right?

Consider three capacitors in parallel, each with a value of 25.0uF. Also consider an Ammeter placed on the first wire coming out of the positive power feed, breaking the circuit there. A potential difference of 4200 V is then established through the circuit. How many coulombs pass through the ammeter? Can you explain your answers?

A parallel-plate air-filled capacitor having area 40 cm^2 and plate spacing 1.0 mm is charged to a potential difference of 600 V.

Find (a) the capacitance, (b) the amount of excess charge on each plate, (c) the stored energy, (d) the electric field between the plates, and finally (e) the energy density between the plates.

What equations did you use? Can you explain your work? Thanks and good luck! :)
