Pascal ka qanoon yeh kehta hai ke jab kisi band (closed) fluid par pressure lagaya jata hai, to woh pressure bina kisi kami ke har simt (direction) mein barabar taur par transmit hota hai. Yani agar aap kisi liquid (jaise pani ya oil) ko kisi band container mein dabao (force) lagate hain, to woh pressure poore liquid mein equally spread ho jata hai. Simple alfaaz mein: “Band fluid par lagaya gaya pressure har jagah barabar hota hai.” Formula: Pressure ka formula hota hai: P = F / A (jahan P = pressure, F = force, A = area) Pascal’s Law ki Applications (Roman Urdu mein): Hydraulic Press Is machine mein choti force ko barhi force mein convert kiya jata hai. Yeh factories mein heavy cheezain dabane ke liye use hoti hai. Hydraulic Jack Iska use gari ko uthana (lift karna) ke liye hota hai, jaise tyre change karte waqt. Hydraulic Brakes (cars mein) Jab aap brake pedal dabate hain, to fluid pressure tyres tak barabar pohanchta hai aur gari ruk jati hai. Hydraulic Lift (elevators/workshops) Workshops aur buildings mein heavy platforms ya lift ko uthane ke liye use hota hai. Syringe (injection) Jab syringe ka piston dabaya jata hai, to liquid pressure ke through bahar nikalta hai.
