Archie: The mechanical advantage of a pulley system can be analyzed using free body diagrams which balance the tension force in the rope with the force of gravity on the load. A force balance on a free body that includes the load, W, and n supporting sections of a rope with tension T, yields . . .
Thus, the mechanical advantage of the system is equal to the number of sections of rope supporting the load.
Me: No, listen, I totally get what you're saying, the red one is easier
Today we took a side trip to Moose Jaw, the home of the world's largest moose statue, Mac the Moose. Now, I've seen large moose statues before. Who hasn't. But wow, this one was exactly the same as the others, just slightly larger.
This was followed by a visit to the Moose Jaw tunnels and the Passage to Fortune tour. This tells the tale of the appalling conditions early Chinese immigrants to Canada lived in. During the tour the guide takes on the character of a ruthless, racist laundry manager who despises the Chinese immigrants but must tolerate them because the owner insists on using the cheap labour. To be quite honest I didn't see much of a difference between the character and the guide. I told Archie that since she's possibly the only Chinese person that's ever taken the tour she should demand restitution on behalf of her people.
