Question

A pencil sharpener has a handle with a radius of 1.5 cm. The sharpening mechanism has a radius of 0.5 cm. What is the IMA of the pencil sharpener?

A-0.33
B-0.5
C-3
D-5

Answer 1

the answer is A I believe

Answer 2

Answer: The correct answer is option C.

Step-by-step explanation:

IMA (Ideal Mechanical advantage) is defined as ratio of input distance to the output distance.

`IMA=(D_I)/(D_O)`

Radius of the handle of the sharper =
`D_I` =1.5 m

Radius of the sharping mechanism =
`D_O` =0.5 m

`I.M.A=(D_I)/(D_O)=(1.5 cm)/(0.5 cm)=3`

3 is the IMA of the pencil sharpener. Hence, option C is correct.
