Question 366394: 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 on each side; that is,
w1x1 = w2x2This equation is called the law of the lever.

A plank 35 ft long rests on top of a flat-roofed building, with 5 ft of the plank projecting over the edge, as shown in the figure. A worker weighing 245 lb sits on one end of the plank. What is the largest weight that can be hung on the projecting end of the plank if it is to remain in balance?

the worker is six times the distance from the fulcrum as the projecting end

so the largest balancing weight would be six times the worker's weight
