Here are 20 questions and answers about hydraulic projects and Pascal’s law, suitable for an science exhibition: Q: What is Pascal’s law? A: Pascal’s law states that any external static pressure applied to a confined, incompressible fluid is transmitted evenly throughout the fluid in all directions without loss. Q: Who formulated Pascal’s law? A: The … Read more
Pascal’s law is applied daily in hydraulic systems, such as in vehicle brakes, where a small force on the brake pedal is transmitted to multiply stopping force at the wheels. Other applications include hydraulic lifts at auto shops, hydraulic jacks for lifting heavy objects, and hydraulic presses used in manufacturing Hydraulic Brakes When you press the … Read more

Concept / Principle: This project is based on infrared motion detection — it senses changes in infrared radiation (heat) caused by a moving object like a human body.When motion is detected, it activates an LED light and a buzzer, simulating a security or automatic light system. Scientific Principle: Infrared sensors detect IR radiation emitted by … Read more
