Thanks BajaX04, Thats a dam good read. =]

 

The top speed of the dragster is not important. At 4.437 seconds the stock car is at 1301.5'.The drag car has crossed the finish line at 1320'.

Now 3 men went to a hotel and asked for 3 seperate rooms, The hotel manager said I am sorry there is only 1 room left and it is $30 for the night, so each man paid $10 (3*10=30) and went to the room. The manager thought that he should give the men a discount so he gave the Bell boy $5 and told him to take it to the men. The Bell boy did not know how to divide $5 3 ways so he put $2 in his pocket, and gave each man back $1, Therefore each man paid $9. 3*$9=$27+$2 in bellboys pocket= $29 WHERE IS THE OTHER DOLLAR?

 

Isn't it amazing how if you control the path you take people down how much influence you have on the destination (or the conclusions that they draw?)


The way you tell the story does make you stop and think, maybe 1+1 really does equal 3.lol[img]i/expressions/face-icon-small-happy.gif[/img]

Some people make a good living doing math the way you just did[img]i/expressions/face-icon-small-happy.gif[/img] Thanks for the entertainment

 

All three men were married, and the dollar was divided by their wives. It's not so much a math problem as a metophysical phenomenal experience. To truly understand this, you don't need any special educational background, just need to be married.

 

Giving back 5 dollars makes the room 25 bucks. Therefore, each man pays 8.333333333. [img]i/expressions/face-icon-small-smile.gif[/img] Unless, one of the men just throws in an extra buck so they dont have to find change. [img]i/expressions/face-icon-small-happy.gif[/img]

 

Reading one of the dragster forums, a very knowledgeable fellow described the acceeleration process for a top fueler. The clutch is slipped mostly to keep the engine rpms up. The engine timing is retarded to keep the engine torque down during the first few seconds. After the fueler has accelerated and the clutch has locked, the engine timing is advanced till it creates full HP. So it is not simply the clutch. Since this is the case, the clutch should be locked as soon as possible after launch. The higher the engine torque.. the sooner the clutch can be locked. The reason is that torque breaks the tires loose.

The Schenck W6300 water brake will easily handle these engines. That is a standard dyno by Schenck (Horiba now). Put one of these on each wheel as a power train dyno, and you can easily hold back the fueler.

Now the reason I say that the acceleration is probably linear in the second half is that there are two major sources of non-linearity related to the acceleration. The first term is the force due to air drag on the frontal area of the fueler. The second force is the downward force generated by the wing on the rear tires. Both forces are proportional to the velocity squared. The air drag creates a force that attempts to slow the fueler. The wing provides downward force that allows the engine to put more force through the tire patch. Given that the engine has the power to spin the tires at will, the frontal drag works against the engine; however, the downward force of the wing works for the engine.
