We upgraded vBulletin to version 6 and with each new version come changes in appearance and functionality. Let me know if something is not right. - Dave
This is to notify all our members that since our recent software upgrade the system is not sending out any emails. This includes birthday emails, membership expiration emails and new Private Message notification emails. We recommend that all paid members check the date that they last paid as you will not get any warning that your membership is expiring. The system is also not sending out email notices when a new user signs up. If you just signed up you will not be notified via email that your membership has been accepted. Please be patient as it may take longer than usual to process your application. Our webmaster Dave Dare is aware of the problem. Hopefully it is fixed sooner than later. - John
The shock absorbers and struts are cycling up and down whenever a car moves. The shock rod moves in and out and seals retain the oil and keep it moving through the right channels. Approximately how many times will a shock or strut have cycled after 50,000 miles?
A. 2.5 million times
B. 25 million times
C. 87 million times
I will tell you the answer after more members have a go at this!

This answer depends on the bumpiness of the roads. The ones in New England would cause this answer to be upped by a factor of 100 or so! Down your way it might be lower.
I would say 50 x per mile or one cycle every 100 feet of driving which equates to 2.5 million. The 25 million seems a bit high which would be every 10 feet of travel. The 87 million cycles would be a schock movement every 3 feet of travel which seems a bit too high.
I'm with JohnG. The first answer is once every 35-meters (or yards). I'm in the city and don't have any RR tracks. So, the first answer is too high (for me).
How long of a stroke are we talkin'? Cracks in the cement? They might stroke 1/4", or not at all, depending on the softness of your tires.
Cement driveway approaches? One inch.
Country washboard dirt roads in the spring? A thousand times per mile.
Now this is interesting, It's like trying to work out the ANGLE of the DANGLE to get the HYPOTENUSE of the TRIANGLE to equal the SINE of the COSINE to get the TANGENT.
Now to get serious.
50 per mile = every 35 yards = 2.5m over 50 years approx.
"" 17 1/2 = 5m """""""""""""""""""""""
"" 8 3/4 = 10m """""""""""""""""""""""
"" 4 3/8 = 20m """""""""""""""""""""""
"" 2 3/16 = 40m """""""""""""""""""""""
"" 1 3/32 = 80m """""""""""""""""""""""
"D" Is out of the question, as the diameter of the wheel is over 2 yards. I don't think it would happen every half of the wheels revolution.
"B" I would think is not right either as it would only work out around two revolutions of the wheel, unless it's on dirt rough roads.
"A" Is my answer, but if there were more choices I would have gone with 5-10m, also it would have helped knowing the condition of the surface.
Ya'll seem to be having fun with this. I think I will let this run into Sunday and then Sunday night give you the answer and the source for the answer.. Some of you have guessed right!
This one is a True/False test to see what you know about these subjects.... Just list them 1-5 as T or F... Good luck!!
How do you rate yourself on the car care awareness scale? Here's an opportunity to find out with our true/false winter maintenance quiz.
1. When the engine cranks but won't start when you turn the key, the problem is a corroded battery connection.
2. Keeping the gas tank above half full helps prevent accumulation of moisture in the fuel system.
3. Before starting out in severely cold weather, let the engine run for at least five minutes.
4. If your heater doesn't warm up your car as it should, your engine may need a new thermostat.
5. A four-wheel drive vehicle can stop twice as fast on ice or snow as the same vehicle with two-wheel drive.
