on the basis, a given figure, calculate rfficiency of the lever. ​

On The Basis A Given Figure Calculate Rfficiency Of The Lever class=

Sagot :

Explanation:

here,load=100N

effort=200N

distance travelled by load=2cm

distance travelled by effort=10cm

Now, output work=L*Ld

=100*2

=200g

Again,

input work =E*Ed

200*10

2000j

again, efficiency = output work/input work*100%

200/2000*100%

=10%
