Power, Torque and Traction
A higher gear equals more traction under certain conditions. I learned this driving a manual (Stick-shift) transmission car in the late 1950s. The engine puts out torque, or twisting power, and torque is what moves the car forward. But only if the tires are gripping the road surface, if the wheels start to spin on ice, snow, or soft ground, then torque is reduced to zero, and the car goes nowhere.
The torque the engine produces is multiplied by the transmission, with the first gear (Lowest) increasing the torque the most. Therefore, first gear is engaged when starting out from a standstill as more torque is needed to move the weight of the vehicle. Once the car is rolling, less torque is required so the driver shifts up through the gears to eventually reach top gear, which puts out the least amount of torque, but transmits more revs, or speed.
If the car is stuck in mud or deep snow, the driver can sometimes get out by starting from a standstill in 3rd or 4th gear, thus reducing torque. He then pushes the clutch pedal down to disengage the clutch, revs the engine a little, and then allows the clutch to engage slightly so the clutch is slipping.
In normal circumstances, if the driver were to allow the clutch to fully engage, the engine would most likely stall because the load would be too great. But by slipping the clutch the driver is limiting the power going to the wheels. As the clutch slowly engages, torque is transmitted to the wheels gradually, just enough to move the car, but not applying too much torque so the wheels start to spin.
Now let’s fast forward from what I learned from driving a stick-shift in the 1950s, to what I learned riding cyclo-cross in the 1970s, and bear with me, there is a connection.
I was running my frame building business just outside Worcester in the West Midlands area of England. A good place to be in the bike business, as this area was a hotbed of British cycle racing, including cyclo-cross. From October to January there were events every weekend within easy driving distance.
Business slowed in the winter months, my commute to work on my bike, and a two-mile run on foot every evening was enough training, coupled with a cyclo-cross race each Sunday. I always reckoned a one-hour cyclo-cross race was the equivalent of 80 hard miles on the road. That is what my legs always felt like after a race.
There were all class of riders in these races. Professionals rode with the amateurs, and after a bunch start, the events soon strung out to a procession around a one mile or so course. I was in my early forties and still pretty fit, plus over time I gained a cyclo-cross skill set that allowed me to beat riders who were younger and faster on the road.
Some of the bigger events in the Birmingham area had enough prize money that some professional riders from Belgium and other mainland European countries would come across and enter. These guys were in a different class all together.
On a one mile course I would expect to be lapped at least two or three times during a race by the leading pros. I remember this Belgian rider went past me having caught me on my second lap, he then passed me every second lap. In other words, he was riding at twice my speed.
One time I was passed going up a steady incline through deep mud, I was in a low gear struggling to keep moving, and as this guy went by, I noticed he was on his smallest sprocket, probably 13 or 14 teeth. While my wheels were losing grip, slipping, and spinning, he appeared to be gliding across the top of the mud. Which of course was exactly what he was doing.
I remembered my old driving lesson that while my lower gear gave me more torque, it was of little use if I did not have traction. His higher gear equaled more traction, plus with his speed and momentum he was going so fast there was less time for him to sink in the mud.
I was recently reminded of this story watching Wout van Aert perform in the Tour de France. Setting an unbelievable pace on mountain stages, shelling some of the world’s best climbers out the back of the peloton. (Above,)
Not really considered a pure climber, certainly not built like one. The other thing is Van Aert won several stages in a sprint. Former World Cyclo-Cross Champion, he must have built up a tremendous core strength riding big gears through the mud in the manner I described earlier.
He certainly developed a big engine that produces a lot of torque.
Trying not to rush getting older
I read somewhere that people do not grow old, they become old when they stop growing. I think back to when I turned fifty, I hated it. I hated the way I looked, I hated my life, and really, I hated myself. I was older then than I am now.
Here I am, close to 35 years later, and my attitude has done a complete 180. Instead of hating my life and having to make a living, I am retired and so I do not have to “Make” anything. I simply live life, enjoy life, and in the process because my needs are less, my needs are met, I manage to comfortably get by.
I am so busy all the time, I wonder how I ever found the time to make a living anyway. I have a purpose in life, and that is essential. A reason to live, to exist, a reason to chew through the restraints and get out of bed every morning.
I work hard at keeping myself healthy, I cannot afford to get sick. I eat a simple plant based diet, and that alone saves me money, Meat is expensive, and with the money I save by not buying it, I can afford to buy the best in organic fruits and vegetables.
My family, friends and loved ones, are my reason to live. I have grandchildren, and even great grandchildren I have yet to meet. I would like to do that one day. I have many good friends I look forward to seeing again. I measure my wealth not by money in the bank, but by those who will miss me when I am gone.
I also see this as a reason to get through this damnable pandemic, and we will. This too will pass. I was scheduled to speak at this year’s NAHBS but it was canceled due to Covid-19, I would like to have the opportunity to do that again sometime.
This pandemic may seem like a long haul, but as a child I remember WWII, and that lasted five years, It didn’t affect me, I was a child and at time I knew nothing else other than there was a war going on. But it passed as all things do, and possibly when this is over, we might learn something from it.
Every day I exercise my body, without my body, where will I live? I also exercise my mind, writing this is making me think, mind calisthenics if you will. That alone makes the effort worthwhile, and if I can bring a little joy into someone else’s life, entertain, inspire thought, that is an added bonus. Helping myself, while communicating with others, isn’t that what those who created this almighty mess that is the Internet and Social Media, intended?
It saddens me to see our country so divided, and it does not have to be that way. I have friends on both sides of the political spectrum, I love them all equally, for the way they treat me, and the way they make me feel when we are together. If they choose to post their political views on social media, it doesn’t mean I should rush to un-friend them. They are still the same person I love as a friend no matter what their views.
However, people who try to force their views on me, change me, or read into my views some political agenda, I can do without that and I will try to distance myself from that person. There is an unwritten, unspoken agreement, I will respect your views if it does not affect me in a negative way.
I get the feeling that some people need an affiliation to this or that political/religious/conspiracy belief group in order to feel they belong to something; maybe it satisfies some primal tribal need, and there is not necessarily harm in it unless they become victims of their own fantasies.
In the meantime, I will continue to believe in myself and a few close friends who share the same values in life. I cannot right all the problems in the world, but I can do my best to keep those problems outside my own world. I gave up on World Peace a long time ago, but I will never give up on inner peace.
