Law of the Lever The figure shows a lever system, similar to a seesaw that you might find in a children’s playground. For the system to balance, the product of the weight and its distance from the fulcrum must be the same in the same on each side; that is,
This equation is called the law of the lever and was the first discovered by Archimedes (see page 831).
A woman and her son are playing on the seesaw. The boy is at the one end, 8 ft from the fulcrum. If the son weighs 100 lb.and the mother weighs 125 lb., where should the woman sit so that the seesaw is balanced?

The region of interest lies between x = 0 and x = 5, and y 0 and y = 5. Your tasks are the following: = 1. Analyze how the elevation changes with respect to x and y. To find the elevation changes, calculate the partial derivatives of the elevation function z with respect to x and 2. Calculate the total volume of soil above the 0-level (z region of interest. = y. 0). To do so, integrate z(x, y) over the wholearrow_forward
