- Q: A power house, P, is on one bank of a straight river 200 m wide, and a factory, F, is on the opposite bank 400 m down stream from P. The cable has to be taken across the river under water at a cost of $6/m. On land the cost is $3/m. What path should be chosen so that the cost is minimized?
- Call the point across the river from the power house P' Call the point of intersection of the cable with the opposite bank C, which defines right triangle PP'C Let x be the distance from P' to C The two legs of triangle PP'C are 200 and x So the hypotenuse (the distance the cable travels underwater) is sqrt(200^2 + x^2) The distance the cable travels along the shore is (400 - x) (the distance from C to F) cost under water: 6sqrt(200^2 + x^2) cost on land: 3(400 - x) 1200 - 3x Total cost 6sqrt(200^2 + x^2) + 1200 - 3x Find derivative of cost: 6(2x) / (2sqrt(200^2 + x^2)) - 3 6x/sqrt(200^2 + x^2) - 3 Where derivative 0 will be a min for the cost 6x / sqrt(200^2 + x^2) 3 2x sqrt(200^2 + x^2) 4x^2 200^2 + x^2 3x^2 200^2 x^2 200^2 / 3 x +/- sqrt(200^2 / 3) +/- 200 / sqrt(3) but discard the negative root (since this won't be the minimum cost), so the distance from P' to the cable hitting land should be 200 / sqrt(3) 200 / (3^(1/2))
- Q: I have been considering the Power Pak from Banks Engineering (with Compression brake), for my 99 Cummins 24 valve. With automatic tranny.Does any one out there have any personal experience with this modification, and will it void the remaining engine waranty on my Deisel engine?
- its a good system to have but it will affect the warranty on it,any modifications to it will affect it,you can call a dealer though and ask them to be sure,but i looked over the warranty for these,and from what i can tell it says any modifications can void the warranty so id call a dealer to be sure on it,,good luck.,,PS i haven't done any modifications to the older one and very few to the newer one,most people want to keep the warranty in affect as long as possible.

- Q: How dramatically did President Jackson change the balance of power between the three branches of government? Did he significantly expand the power of the executive branch?

- Q: I see many computer UPS out in the market, but do UPS meant for whole houses exist? I live in a small town, and we have brownouts often, lasting for a split second up to 20 seconds at a time. A lot of our electronics get messed up 'coz of this. We also have a back-up generator. Is there a way to connect the generator to the UPS so that if we get a blackout lasting for hours at a time, we have time to turn on the generator without power dying.
- Yes, You can use of heavy powered commercial UPS for your whole Houses. But it's so Very expensive for using in the whole house. As you are asking, you can also connect Riello UPS products from your generator directly.
