    先聲明一下,Bar是壓力單位,不是力量單位

    圖片參考:http://l.yimg.com/f/i/tw/ugc/rte/smiley_1.gif

    已知:

    活賽直徑﹝其實應該扣除桿部分﹞D=50mm=5cm

    壓力P因為 1bar=1.0197kgf/平方公分

    所以 5bar=1.0197kgf/平方公分*5=5.0985 kgf/平方公分

    活賽面積A=3.1416/4*D*D= 3.1416/4*5*5 =19.635平方公分

    圖片參考:http://l.yimg.com/f/i/tw/ugc/rte/smiley_1.gif

    計算:

    出力F=壓力P*面積A

    =5.0985kgf/平方公分*19.635平方公分

    =約100 kgf

    活賽

    為活塞之筆誤

    以上出力為理論計算之出力

    實際出力應扣除摩擦等等阻力,設計成約7成左右即可。

    5*5*0.784*5=98Kg
