An energy efficient air conditioner draws 7 amps in a stadard 120 volt circuilt. it costs $40 more than a standard air conditioner that draws 12 amps. if electricity costs 8 cents per kilowatt hour, how long would you have to run the efficient air conditioner to recoup the difference in price?

you can alter the wood by adding water or glue to it but it has to appear the same in the finishing results, so you can add iron to it because itll look different and no you cant put paint on it to make it look the same as it was before

Hey,

What's the engineering reasoning behind why sometimes shear stress is neglected if it is significantly smaller than,say, bending stress. So I guess what I am asking is that why does shear stress come out soo small?

like for example, a bike pedal with crank has 300lbs vertical only force applied to it, and made a cut and analyzed it. The bending stress due to bending moment was 50kpsi while shear stress was 1.7 kpsi.

We also made that assumption when I took streghts of materials for many of the cases. I still don't know why it is safe to make that assumption.

Thanks

If either husband or wife paid the premium that was due, then the policy is in force and the cost of the accident was covered. If the cost of the accident was covered, they were not forced into bankruptcy. But they were forced into bankruptcy. Therefore, the husband did not pay the premium that was due.

...in a household in place of a standard 60 W bulb over the course of one week, where each bulb would be on 10% of the total hours of the week? What would the total savings to consumers be in the US, assuming all of 50 million households in teh US try this with one bulb each? Assume a utility rate of $0.10 per KWh.

Hey,

What does it mean when the force is fully reversed?! Will the force/torque applied on the bike pedal/crank considered fully reversed?! I know it is, but I don't know why. In my analysis, I used weight of the rider as the only force applied to the pedal as it rotates, and that force is fully reversed to calculate factors of safety in the pedal/crank-arm.

How would I explain the logic behind that in the report?! Any ideas?

Thanks!

how does it work? I see all those grains on the fields just getting separated so finely and getting thrown off into loaders and i'm curious. I've checked how stuff works.com already, but no luck. Maybe i'm not using the correct keywords?

when i turn on the switch nothing happens. does anybody know what could cause it and what i can do to fix it? i think it is single phase or something and was left outside with a big plastic sheet over it. i havent used it for about 4 months now, but it was working fine before. i have checked the fuse and connections and they all seem fine

In case of natural draft cooling towers, it is in hyperbolic in section; basically it can take load (wind, self weight)
How a hyperbolic section can take more load compared to conical or cylindrical sections.

As we know, in case of rectangular sections the moment of inertia is high and hence the stress it can handle it is also high according to bending moment equation, but why we prefer a i section beam.
