AI Thread Summary
The discussion revolves around a homework question regarding the relationship between torque direction and gear movement. The original poster is confused about why the torque direction is indicated as opposite to that of the gears. Visual aids are provided to illustrate the question. Participants are likely to clarify the principles of torque and gear mechanics. Understanding the mechanics of torque in relation to gear rotation is crucial for solving such problems.

Here is my homework question and answer. I am not sure why the answer shows that the direction of torque is opposite of the gears.

Thread '2:1 Pulley Question'

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...

Thread 'Why do all my clocks run slow?'

Hi. I noticed that all electronic devices in my household that also tell time eventually lag behind, except the ones that get synchronized by radio signal or internet. Most of them are battery-powered, except my alarm clock (which runs slow as well). Why does none of them run too fast? Deliberate design (why)? Wrong temperature for quartz crystal? Decreasing battery voltage? Or just a coincidence?
