A lever with an output arm of 0.8 meter has a mechanical advantage of 6. What is the length of the input
arm?

From the law of the lever: mechanical advantage= input arm : output arminput arm- aoutput arm-b[tex]mechanical\ advantage= 6\\\\
6=\frac{a}{0,8}\ \ |*0,8\\\\
6*0,8=a\\\\
a=4,8m

[/tex]Input arm is equal 4,8m
