Thank you for your reply! The total length of the bar turned out to be 29 cm. the distance from the load to the force is 21.5 and the distance from the force to the fulcrum is 7.5. I may have not done the math correct. so in theory for the class 2 lever if the over all length was 30 cm then the length from load to fulcrum would be 12 and the distance from force to load would be 18. is that correct?

I am trying to coach kids in science olympiad and hate to disappointment them. I attached a file. I need to use to class of levers in conjunction to create an IMA of 5. Is the attached photo correct? Thanks for any help you can give.
