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.
