Thread: maximization problem of sorts

1. Alright, I want to maximize the variable c in this drawing where h and c change, but A and B are constants. I'm not sure how to explain this any better, and I'm not sure how to afix this to a related rates problem.

You are going to have to explain that figure. I see no clear relationship between c and any other dimensions.

4. it's actually a rather crude diagram of the movement of the throwing arm of a trebuchet I'm currently designing. I have a fixed length arm that has a counter weight(cw) at one end, and the projectile in a sling on the other. What I was trying to figure out was, as the cw falls, the throwing arm rotates about an axle (that is the line A in the diagram) and drops the tip lower towards the ground until it hits a max and then begins it's ascent back up untill it's level with axle, and at that point I already have figured out. I'm just curious about a method to solve this little problem, and I assume it has somewhere in a relation between the length A and the length B, just not entirely sure how to handle it.
