Homework Statement



Calculate the effort required to lift a load of 1962N using a third order lever with load 5m distance from effot and fulcrum 1m distance from effort.

Homework Equations



i used the following,

large distance x small effort = small distance x large effort

The Attempt at a Solution



so, 5m x small effort = 1 x 1962

effort = 1962/5

= 392.4 N

and giving an MA of 5. 1962/392.4.

Am I along the correct lines here? Any help much appreciated.
