Class 9 Physics | Chapter 6 Mechanical Properties of Matter | Numerical 6.11 | Hydraulic Press | New Book 2025 In this lecture, we solve Numerical 6.11 from Chapter 6 Mechanical Properties of Matter of Class 9 Physics (Punjab Textbook Board – New Syllabus 2025). This numerical is based on pressure in a hydraulic press and the relationship between pressure, force, and cross-sectional area. The question states that the pressure in a hydraulic press is increased by an additional 10 N cm⁻². We are asked to calculate how much extra load can be supported by the output platform when its cross-sectional area is 50 cm². 📘 Given Data: Additional pressure = 10 N cm⁻² Area of output platform = 50 cm² We use the formula: 👉 Pressure = Force ÷ Area Rearranging: 👉 Force = Pressure × Area Substituting the given values: 👉 F = 10 × 50 👉 F = 500 N ✅ Final Answer: 500 N 🔎 What You Will Learn in This Video ✅ Relationship between pressure, force and area ✅ Application of Pascal’s Law ✅ Working principle of a hydraulic press ✅ How to calculate force from pressure ✅ Step-by-step numerical solving method ✅ Correct use of SI and practical units ✅ Board exam solving technique 📚 Concepts Covered ✔ Pressure ✔ Force ✔ Cross-sectional Area ✔ Hydraulic Press ✔ Pascal’s Law ✔ Mechanical Properties of Matter ✔ Hydraulic Machines ✔ Physics Numericals ✔ Board Exam Preparation 🎯 Why Numerical 6.11 Is Important ⭐ Important numerical from Chapter 6 ⭐ Strengthens the concept of pressure ⭐ Helps understand hydraulic machines ⭐ Useful for board examinations ⭐ Improves numerical-solving skills ⭐ Helpful for MCQs and short questions 👉 Watch the complete Chapter 6 Mechanical Properties of Matter Playlist for complete preparation. 👉 Like 👍 | Share 🔁 | Subscribe 🔔 for more Class 9 Physics lectures. 9thclassphysicsnumerical6.11,Class9physicsnumerical6.11,9thclassphysics,chapter6mechanicalpropertiesofmatter,numerical6.11class9physics,hydraulicpressclass9,hydraulicpressnumerical,pascalslawclass9,pascalslawnumerical,pressureclass9physics,pressureandforce,forceandareaphysics,hydraulicmachinesclass9,hydraulicpressureclass9,class9physicsnewbook2025,punjabboardphysics,physicsnumericalclass9,mechanicalpropertiesofmatter,class9physicsenglishmedium,physicsboardexam2025,pressurecalculationphysics,forcecalculationphysics,siunitconversion,physicscalculationclass9,class9physicslecture,physicslearningclass9,scienceclass9physics,physicsnumericalpractice,class9physicssolutions,annualexamphysicsclass9,class9physicshelp,basicphysicsconceptsclass9,physicsnumericalsolution,hydraulicpressproblem #9thclassphysicsnumerical6.11 #Class9physicsnumerical6.11 #9thclassphysics #chapter6mechanicalpropertiesofmatter #numerical6.11class9physics #hydraulicpressclass9 #hydraulicpressnumerical #pascalslawclass9 #pascalslawnumerical #pressureclass9physics #pressureandforce #forceandareaphysics #hydraulicmachinesclass9 #hydraulicpressureclass9 #class9physicsnewbook2025 #punjabboardphysics #physicsnumericalclass9 #mechanicalpropertiesofmatter #class9physicsenglishmedium #physicsboardexam2025 #pressurecalculationphysics #forcecalculationphysics #siunitconversion #physicscalculationclass9 #class9physicslecture #physicslearningclass9 #scienceclass9physics #physicsnumericalpractice #class9physicssolutions #annualexamphysicsclass9 #class9physicshelp #basicphysicsconceptsclass9 #physicsnumericalsolution #hydraulicpressproblem
