### How does the length of effort arm affect the amount of effort needed to lift an object?

The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.

### Why do some helicopters have more than 4 blades?

The number of blades required is proportional to the amount of lift required. There are several factors that affect the amount of lift produced by rotor blades. They are the shape of the air foil, the rotational speed, the angle of attack, the length of the rotor blades, and the strength of the blades. All of these have practical limits. Adding an additional blade helps keep all these parameters within practical limits.
