levers planes and axis

Question 1

equation of mechanical advantage

Answer 1

mechanical advantage=effort arm/ resistance arm

Question 2

effort

Answer 2

force applied to move the load

Question 3

fulcrum

Answer 3

the fixed point or axis on the lever

Question 4

load

Answer 4

the weight that the lever is moving

Question 5

rule no 1 in mechanical advantage

Answer 5

when the effort arm is shorter than the load arm it is low mechanical advantage
