bimetallic behavior - THERMAL EXPANSION effect

Basics of BIMETAL

Bimetallic Strip bends on heating

Bimetal again

Bimetallic plate opening chamber.

Bimetal acting in reverse

Cooling straightens bimetallic strip that pushes piston

MATCHED THERMAL EXPANSION WITH THERMAL CONTRACTION VIDEO COMING SOON

There exist materials that expand on cooling,!

Coanda Effect (Age 17-19+)

In Aircraft Cabin

In Aircraft Cabin

Escape Velocity - Gravitational Force effect (17+)

Rocket propelled < Escape Velocity

Rocket propelled > / = Escape Velocity

Exercises-age group mentioned each one

for Kids@17 - 20 : A real time video of a roof-top. What is this?

for KIds@15 - 20 : Forces shown on block as it slides down incline are not shown correctly. What is wrong?

for Kids@15 - 20 : Observe the Free Body Diagram (FBD) in Video (below one) of Block. In particular observe the 'Tension, T' in rope lessening as it 'lags' down. Try to use to apply onto a wire with clothes hanging to dry.

STEM@ Fly

Flapping Bird Aircraft- This design will not lift above ground. Detect the technical error.

This design can lift above ground and fly.

This design can lift above ground and fly (above one)

A small success of above flapping wing design- not a very good flight though!

Super Capacitor powered, fixed wing flight, biased adjustments to make it circle. No RC.

FOLDABLE AIRCRAFT assembled. Carried as a slim machine in bag on bike until 'runway'. FLYING FOOTAGE LOST, APOLOGIES

Designs in progress: Stabilizer built with parts, each of different material (Left) , Foam used to soften landing, reduce landing distance.
