Question

A machine has a mechanical advantage of 4.5. What force is put out by the machine if the force applied to the machine is 800 N?

A-0.006 N
B-180 N
C-805 N
D-3600 N

Answer 1

The answer is d

Step-by-step explanation:

Answer 2

The correct answer to the question is D).3600 N.

CALCULATION:

As per the question, the mechanical advantage of the machine MA = 4.5.

The force applied to the machine
`F_(i) =\ 800\ N`.

We are asked to calculate the output force of the machine .

Let the output force is denoted as
`F_(o)`.

The mechanical advantage of a machine is defined as the force amplification of a machine by using certain mechanical devices.

Mathematically it is defined as the ratio of output force to the applied or input force.

Hence, mechanical advantage MA =
`\frac{f_(o)} {f_(i)}`

Hence, the output force is calculated as -

`f_(0)=\ MA* f_(i)`

`=\ 4.5* 800 N`

`=\ 3600\ N` [ANS]

Hence, the output force is 3600 N.
