PHYSICS LEVER/IMA

Question

Create a class 1 lever with the fulcrum at 50cm mark, have the weight at 100cm mark, and the effort force at 0 cm. 

4a)What is the mechanical advantage of the lever

4b)move the fulcrum to 60cm what is the mechanical advantage now

PART 2

list the mechanical advantage of each of the fulcrum at a 10 centimeter denomination

(10,20,30,40,70,80,90)

(you don't have to do part two but id like to know the steps of solving these)

Answer 1

The mechanical advantage of a class 1 lever is given by the ratio of the distance of the applied force from the fulcrum (La) to the distance of the output force from the fulcrum (Lo).

a. La = 50 cm Lo = 50 cm MA = 1

b. La = 60 Lo = 40 MA = 1.5

Part 2 one example. If the fulcrum is at 10 cm, La = 10 Lo = 90 MA = 0.11

I think you can work the others out yourself.
