Which statement is true of hydraulic tools? Hydraulic tools: a. Are powered by gasoline. b. Can cause electric shock. c. Use fire resistant fluid. d. Work like a loaded gun.

c. Use fire resistant fluid.

Explanation:

Hydraulic tool also known as hydraulic machinery are tools powered by pressured fluid. Most times they are heavy machinery or equipments that transfers high pressured hydraulic fluids into its hydraulic motor and cylinder. This fluid is automatically controlled by control valves and distributed via hoses and tubes. The major reason why companies uses heavy hydraulic tools is due to its ability to transfer huge amount of power within its tubes and hoses

Answer / Explanation:

As related to the question asked, Hydraulic tools use fire resistant fluids.  

It is important that hydraulic fluid used is fire resistant and capable of operating at high temperatures. Hydraulic fluid should not and does not heat up under pressure. Hence, adding this factor to the issues of prolonged exposure to high heat at fire scenes means that there are limited choices of hydraulic fluids for fire engines.

To properly understand the above statement the principle of hydraulic system or tools, we will give the example of a fire fighting system.

Firefighters use hydraulic equipment on a daily basis when they put out fire and rescue people from burning buildings or crashed vehicles.  

The ladder on top of a emergency fire engine truck is raised and lowered by a hydraulic piston that is controlled by the ground crew, with another set of hydraulic hoses controlling the extension of each section of the ladder independently therefore allowing the correct length of ladder to be deployed for each situation.  The ladder position is also controlled by a hydraulic motor that turns the ladder left and right, making it easy to get the ladder in exactly the right place by using all three hydraulic components.

 It is not just the firefighters ladder that uses hydraulic power, but the rescue and cutting tools, as well.  

It is therefor necessary that the choice of a fire resistant hydraulic fluid is very important in fire engines, as by nature they are used in situations where high temperatures and pressure are present.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
