What’s mass?

- is a measure of the amount of matter in a object

2
New cards

Convert mass to weight

mass/1000• (9.81)

3
New cards

Given effort mass + location from fulcrum. Find load mass and its position from the fulcrum

(given effort mass) • (distance from effort force mass/fulcrum) = (chosen mass) • x

4
New cards

Calculating weight

  • W=mg

  • W = (10g) (1kg/1000g) (9.81 m/s^)

How to calculate M.A? (And IMA)

MA:

• resistance force / effort force

IMA :

effort force / resistance force
