Question

A man lifts various loads with the same lever. The distance of the applied force from the fulcrum is 2.00 m and the distance from the fulcrum to the load is 0.500 m. A graph of resistance force vs. effort force is shown. What is the mechanical advantage of the lever? What is the ideal mechanical advantage of the lever? What is the efficiency of the lever? Show your work.

Answer 1

@dslatton is there a graph?

Answer 2

well.. if not I can answer the first question. the second question needs the graph, as well as the third.

question 1)
mechanical advantage = distance from fulcrum to applied force / distance from fulcrum to load. ^_^ so just input those distances and divide and you got the answer to question 1

Answer 3

here it is

Answer 4

great, i'll look it over.
do you understand the first question?

Answer 5

I am so confused about physics

Answer 6

picture time then! ^_^
