Study the table carefully and answer the following questions:
 
Machine Load (N) Effort (N) Load Arm (m) Effort Arm (m)
Lever A \(300\) \(100\) \(0.5\) \(1.5\)
Lever B \(200\) \(100\) \(0.4\) \(0.8\)
Inclined Plane C \(500\) \(250\) - -
 
1. Which machine has the greatest mechanical advantage?
2. If the effort applied to Inclined Plane C is increased to \(300\ N\) while its mechanical advantage remains \(2\), what load can it lift?
