When one door opens...

It's all because of torque! YAY!

I learned at a young age that you can't push a door open near the hinge. You see, my mom would always have to unlock the door, so she stood in front of the end furthest away from the hinge where the lock was located. And I, being the impatient little kid I was, would always try to push the door open from the only other end available: the one near the hinge. Sadly, every time I tried, my little hands and body was never able to open it. (Though sometimes I would push with my mom and pretend that it was all me. Hehehe.)

In addition, today, my dad was carrying our new TV into the house. Somehow he got himself in the door, but he was holding the door open with his head and couldn't move without the door closing on him. After laughing for a little bit (haha), I went to push the door open to help. I was carrying stuff too, so I tried to use my foot. I was too close to the hinge, so the door didn't budge and Daddy was still struggling. Instead of pushing it open, I used my butt to hold it open so he could get inside with no damage.

My difficulty with doors through the years was because of torque. Torque equal radius times the force. With a shorter distance from the pivot point, you need more force to achieve the same torque. I didn't know that as a kid, but now I do.
Yeah. That's my door (Ignore the dust >_<). I stood closest to my broken doorbell, which was not very smart of Little Steph. Luckily I learned eventually.

Today, I also realized that my doorknob is related to this same concept. I won't expand too much on this one, but you can have a picture. I'm sure you get the point by now.

Oh, but if you look carefully in the background, you can see my internet antenna from last week's blog! MIND BLOWING, isn't it?! :D
