Give an example of a system in which people use steam for a mechanical advantage.

Turbines.

Explanation:

Hello,

In this case, we define steam as high-energy vapor water, which has the capacity to be cooled to release energy to a system. For instance, turbines, use overheated steam to produce energy, by feeding the steam to the turbine's rotor blades in order to make the rotate and generate work. As a consequence of the rotation, the steam loses energy, for which it goes out from the turbine at low both temperature a pressure, even do, in some cases it could go out liquid so a condensation may occur.

Regards.

Steam turbines

Explanation:

Mechanical advantage is used to describe the attainment of an amplified force output from a minimal force input

Steam is the water in gaseous form

Therefore, an example of where people use steam for mechanical advantage includes the steam turbines in power generation being turned by steam produced from burning water from a supply.

Here the expansion of the water to steam provides power to drive the the turbines so as to perform mechanical work.
