And remember, we want to say our effort force equals our load force divided by our mechanical advantage. Okay, so let's say that our effort force is 500 newtons, how much can we lift with this …

Triangle A B C, vertices point upper A at negative 3 comma negative 4, point upper B at 1 comma negative 7, and point upper C at 0 comma negative 5. Triangle A prime B prime C prime, vertices …

If you do a search for mechanical advantage, I cover some things on moments and also on torque. So what is moment of force? Well, it essentially is the same thing as torque. It's just another word for it. …
