how to make hydraulic drum brakes working model

hydraulic drum brake system working model for science project exhibition - diy - diypandit

A hydraulic brake uses liquid pressure to transfer force from the brake pedal to the brake drum to stop a vehicle. In this working model, you will show how pressing a “brake pedal” moves hydraulic fluid (water or oil) through a tube to push a “brake shoe” against a “drum” (wheel). Working Principle Demonstrated: Pascal’s … Read more

how to make working model of an electric bell

electric bell working model for science project exhbiition - diy - science project academy

This is a working model of an electric bell. When the switch is turned ON, electric current flows through the circuit, powering the DC motor. The motor rotates the nut attached to its shaft, which hits the steel glass to produce a sound. This demonstrates the basic idea of how electric bells use mechanical action … Read more
