Hydraulic JCB
Pascal's LawThe Pascal's law states that if pressure is applied
at any one point in an enclosed liquid, that pressure is equally
transmitted in all directions within the liquid.

Description: The basic mechanics behind hydraulics is
transferring kinetic energy from one piston to another by pushing water
through the tubing.

Flame Standing Wave Tube (Rubens' tube)
The Ruben's Tube is a physics experiment demonstrating a standing wave. Invented by German physicist Heinrich Rubens in 1905.
Material required : A Long Metal Tube (Perforated along the top), Speaker or Frequency generator, Gas Cylinder, Lighter, etc

Material required : A Long Metal Tube (Perforated along the top), Speaker or Frequency generator, Gas Cylinder, Lighter, etc
Description: A length of pipe is perforated along the top. One ends of pipe is attached to a speaker or frequency generator, and other end connected with Gas Cylinder. When you switch on the gas supply, the pipe is filled with the gas, and the gas leaking from the perforations. Light the gas with the help of lighter.
When the speaker is turned on, it sends a series of waves of air down the tube at the speed of sound, these then reflect off the far end of the tube, so there are two sets of waves moving through the tube in opposite directions. For most wavelengths this does not produce a very interesting effect, but when the length of the tube is a multiple of half the wavelength the two waves add together to form what is known as a standing wave. This standing wave can be seen directly as differences in the height of the individual flames.
Notes : The tube can become very hot during Experiment.
For safety reasons, the Rubens Tube was set up outside. Hydraulic Bridge
The Pascal's law states that if pressure is applied at any one point in an enclosed liquid, that pressure is equally transmitted in all directions within the liquid.
Hydraulic systems use a incompressible fluid, such as oil or water, to transmit forces from one location to another within the fluid.
Material required: Plastic syringes, vinyl tubing, Bridge Model, etc
Description:The basic principle behind any hydraulic system is Pascal’s
Law.
"Pressure
applied anywhere to the body of fluid causes a force to be transmitted
equally in all directions, with the force acting at right angles to any
surface in contact with the fluid."
We can demonstrate the hydraulic bridge using simple plastic syringe for cylinders and small plastic tubing for the hydraulic hose.
