5. Fulcrum is between EF (effort) and RF (load) Effort moves farther than Resistance. Multiplies EF and changes its direction

7. RF (load) is between fulcrum and EF Effort moves farther than Resistance. Multiplies EF, but does not change its direction

9. EF is between fulcrum and RF (load) Does not multiply force Resistance moves farther than Effort. Multiplies the distance the effort force travels

14. MA of an screw can be calculated by dividing the number of turns per inch.
