How much work is required to wind the entire chain on the pulley?

An 80ft length of steel chain weighing 20lb/ft is dangling from a pulley. How much work is required to wind the entire chain on the pulley? In this problem you are to EVALUATE the integral required to answer the question.

change in energy = integral 0 to 80 of 20xdx
the integral = 10x^2+constant
the constant = 0 since 0 work done at 0 feet

10x^2 = 64000-0=64000ft lbs

Does anybody else think Ricky Ponting is the second greatest test batsman?

Is Rick Ponting the greatest test batsman behind only Don Bradman. Pontings stats:
168 Test caps & 13,378 runs
375 ODI caps & 13,704 runs
71 international centuries
Highest Test score: 257 v India in 2003
Won three World Cups
Tests as captain: 77
Tests won as captain: 48
Not only are his stats impressive but he was one of toughest and most competitive cricketers in the game. He thrived under pressure and adversity and played with a beautiful combination of aggressive stroke play and solid defence. He was also a great captain.

I wouldn’t say 2nd. More bottom half of the top 10.

Do you have to distill homemade spirits?

I’m planning on making vodka via the potato method. Do you have to distill it after the fermentation process? Or is that just to give it a stronger proof. I don’t have a still and I don’t wanna buy the stuff to make one. Is it dangerous to skip the distillation process

If you are going to make vodka…then yes…you will have to distill. You are taking a risk if you dont know what you are doing. There are two types of alchohol that stream from making likker. Be sure to keep your temp at 174 and throw away your first few ounces of liquer…it will make you sick. Also be sure you have a complete cooling coil method in place so ya dont blow up the still. Not tryin to scare ya…just hate seeing someone get burnt up over some likker. To get the best likker you want to distill three times to about 180 proof. Then add quality water to cut it down to 100 proof…you will need a hydrometer to get it right on. Keep in mind if you are doing this in the usa …it is a federal offense and i do not suggest in any way anyone attempt to make likker. But good luck…..

Forge welding a knife from a timing chain – Part One

Taking a car timing chain, I cut it into pieces, tack welded the pieces into a billet, then heated and pressed with my home built 24 ton hydraulic press. Part two will show more of the resulting blades.

Where can i make my own necklace?

I drew up this really cool design. It has a similar shape to the detroit redwings logo but much simpler (only a few lines) i really want to get it cut in steel (or some kind of metal) kind of like this:
http://misericordiafoundation.com/wp-content/uploads/2011/11/angel-wing-necklace.jpg
Of course, i want the loop for the chain more in the center or even off to the other side (the narrow side) a little so the wider side angles down a little. It doesn’t really matter if the necklace part is a steel chain or if it is a sturdy black fabric.
I would just like to know if anyone knows a place or a website that could make a necklace like this out of a drawing i provide.

Find a local place that does laser metal cutting, and ask how much they’d want to do it. Alternatively, buy a jewelers saw and start sawing. Add a chain yourself — try firemountaingems.com for some examples.

How can two variables have different means but not be correlated?

A t-test confirmed that two variables had significantly different means, but Spearman said they’re not correlated. One variable is ordinal (strong, weak) and the other is interval (scores). So the strong folks have significantly higher test scores than the weak group, but the "strong" category is not associated with higher test scores? I can wrap my head around these stats. Can someone explain this to me conceptually?

I agree. You are absolutely right. It is a bit confusing my mind also. Let me consult my mentor today evening and let you know tomorrow.

What is the best way to wire my car audio system?

Here’s my deal: I have an Alpine amplifier leading into a sub, also Alpine. The amp is an Alpine MRP-M500. The sub is an Alpine SWS-12D4. Now I know that with the dual voice coil, there are two possible ways to wire it, in series and in parallel. I also know that parallel wiring causes the load to drop to 2 ohms and the wattage to rise. I currently have the system set up to run from the amp to the sub’s dual voice coils in series and it sounds great, but I’m a little concerned about damaging my system. I am also curious as to whether or not it can sound even better. Is there something I can do to boost the system or did I mismatch the two? If I made a mistake, what should I look into, within the same price ranges?

Rewire the voice coils to present a 2 ohm load to the amplifier. It’s more than capable of handling a 2 ohm load and will deliver the full 500 watts RMS it’s capable of opposed to the ~200 watts you’re currently getting out of it with the voice coils wired in series.

AAMOF, there are some concerns of monoblock amplifiers not operating properly at loads higher than 4 ohms. I’ve never seen any proof of it, but regardless it’s not helping anything, especially in your situation.

is it bad to listen to music before a test?

is it okay to listen to music before a test? (IE: math, chem, physics)
My friend says that she never listens to any music before a big test… and her results show
but that can be just her belief

i heard classical music can help get a high test score.

are these true?
try to compare it with studying with music and without music.
do not factor in the amount or how intensely you studied.

Probably it can. But, usually it won’t. Only listen to music without lyrics in it. Lyrics can distract you from remmebering the information.
