Question

In the figure below shows a lever in use.

(a) To which class of lever does it belong?

(b) If AB = 1m, AF = 0.4 m, find its mechanical advantage.

(c) Calculate the value of E.

Open in App

Solution

(a) this is class 1 lever
(b)given
AB=1m and AF=0.4 m therefore BF=0.6 m
$M A equals fraction numerator B F over denominator A F end fraction equals fraction numerator 0.6 over denominator 0.4 end fraction equals 6 over 4 equals 3 over 2 equals 1.5$
(c) Load =15kgf
$E f f o r t space equals fraction numerator L o a d over denominator M A end fraction equals fraction numerator 15 over denominator 1.5 end fraction equals 10 k g f$
