I have been told that I am a good test taker and for the first two years of my college career this was quite true. I attribute much of my success in this area to my good intuition, that is to say that the first way I think of to solve a problem is usually the right way. This has been becoming less and less true however much to my dismay, culminating in a disaster this past week.
My intuition is built by passed experience. If it worked before it ought to work now, right? This is why doing all of one's homework is very important. It builds the intuition necessary to perform well in a similar situation. However the intuition gained by doing Heat Transfer homework is not always applicable on a Thermodynamics test. Some of it may be but some of it will definitely lead you down the wrong path.
The previously mentioned disaster is not at all school related but the principles are the same. I am an avid four-wheeler and motorcycle rider. One of my favorite things to do with them is climb steep hills. In the event that I do not make it up a steep hill the failsafe to keep it from flipping over and rolling down the hill is as follows:
- Grab the front brake and allow the engine to die.
- Jump off the bike while holding the brake.
- Hold the bike in a upright position and carefully turn it around.
Most of the time this sequence works perfectly at not flipping over, keeping the bike stopped and not sliding backwards down the hill. The last things you want to do is to stay on the bike and rev up the engine because this will almost certainly cause your back tire(s) to grip the steep terrain and flip you completely over.
Snowmobiles, mind you, are far different.
This past week I got the privilege of snowmobiling with a good friend of mine. To cut to the quick at one point in the day we were traversing a short but steep hill. The hill got quite steep toward the top and the sled I was running did not have the traction to get me to the top. I passed the point of no return (the speed at which I would still be able to turn the snowmobile completely around without stopping on the side hill and rolling over) because it looked as if I would make it. When I slowed to a stop my intuition took over the situation. I let go of the throttle grabbed the brake and was contemplating jumping off when the most surprising thing happened. The snowmobile started to quickly slide backwards down the hill! I tried to ride it out but at one point the front skis turned hurling me off and sending the sled rolling.
So my intuition failed me in how to react to "not making it" up a steep hill on a snowmobile because I applied the wrong basis to the situation. Snowmobiles don't react the same as 4-wheelers when you "don't make it."
However after you "don't make it" they react exactly the same. They come after you with a vengeance. There is still a Me-shaped indent up there where the sled pounded me into the snow on its way to the bottom of the hill. Damages to me were inconsequential but the snowmobile's windshield cracked in several places (I have ordered a replacement).
As it turns out the right way to handle this situation would have been to the last thing that I would do on a 4-wheeler. That is to spin the track until it buries itself in snow making it impossible to slide backward. Snowmobiles, because the are very long end to end, are very unlikely to flip end to end on a hill, even a very steep one, whereas 4-wheelers might flip even if you follow the directions prescribed above.
The lesson here is valuable. It is good for me to realize that my first instinct is not always right. I should explore other options before I commit. As a hope-to-be-soon Engineer I need to have good intuition but I should never stick to my first thought as though it were the only option available. Fortunately for me in a workplace environment I will have more than 19 milliseconds to make a decision on how to proceed unlike the snowmobile incident where instinct took over because I did not have time to think.
