## anonymous one year ago A crowbar of length 1.2 m has its fulcrum at a distance of 0.2 m from the load.Calculate the mechanical advantage of the crowbar.

|dw:1441710291498:dw| Mechanical Advantage =$$\large \frac{ Load}{ Effort}$$ and we know from taking moments about the fulcrum that 1 x Effort = 0.2 x Load
