Week Eight: ...Must Study Harder!

January 14, Monday
It is another three hour session with our Machine Shop instructor. We discussed and reviewed about some of the measuring tools Sir Bong taught us last year. Also, our instructor taught us how to read the tolerance of a round work-piece using the dial gauge.
Listening to my instructor in Machine Shop, I learned how to actually measure the deflection of the gauge. I was surprised to found out that the dial gauge is so sensitive that it could actually measure up to .01mm deflection on the work piece’ surface.
I remember last December 2005, I encountered a similar gauge connected to an arrow straightener—my favorite “armoring” equipment in archery. It is the equipment used to reduce the bends, if not to straighten up, the arrow shaft. I was the club armorer during my 4th year in our school when the coach of Brent, Sir Bambao, lent me this brand new staightener. He taught me how the dial gauge operates while applying my knowledge with the old straightener we are used to. No wonder this arrow straightener is very accurate.
In physics, we moved on to our next topic—free falling body. This part of physics, as I can remember, is the part I missed during my high school. I literally slept, if not listening or not in class, the whole quarter; this is the reason I didn’t understand the concept of projectile motions and uniformly accelerating circular motion that is part of the whole 3rd quarter in our Physics in the 3rd year. I’m not missing any topic for my physics today—I’ll be attentive this time.
