    Kraft, drücken

    Sources
    Welche Kraft bringt man auf, wenn man mit einem Druck von 300 bar auf eine Fläche von 1x1 cm drückt?
    Comment
    Can I say force for Kraft?

    Does drücken in this context mean to pressurize? Or does pressurize only work with people?

    thx!

    What power do you bring up, when you press on an area of 1cm x 1cm with a pressure of 300 bar?

    oder

    What power do you bring up, when you give a pressure of 300 bar on an area of 1cm x 1cm?

    Suggestionforce, exert a pressure

    "power" is wrong in my opinion. Power, as a physical quantity, implies a reference to time.

    Force ist genau richtig. "Pressurize a pressure" würde ich nicht schreiben.

    Kraft is force
    Druck is pressure

    Welche Kraft bringt man auf, wenn man mit einem Druck von 300 bar auf eine Fläche von 1x1 cm drückt?

    e.g.

    What is the resultant force when a pressure of 300 bar is exerted on a surface of 1x1cm

    Kraft ist unbedingt "Force", denn "Power" ist die Leistung. Also komplett etwas anderes.

    Stimme #3 + #4 hundertprozentig zu.

    PS: It is a force of 3000 N :-))

    My clever questionnaire says the answer is 30 kg. ;)
    But I have no clue if this equals 3000 N ;)

    This clever questionnaire does what I can't stand at all: It mixes up force and mass.

    *edit*

    In addition, it's completely wrong - with a gravity of 9,81 N/kg, Snake2000's 3000 N (which is the correct answer), would correspond to 306 kg!

    I probably should tell the person who wrote it..maybe it's just a slip of pen.
