INVENTIONS THAT NEED INVENTING...

[BOB D.O.L.E]

Nostrall hair trimmers.

 

[Bahco]

You mean nostril

Haven't scissors been invented Bob

I use mine every day

1/4 drill on slow speed ? ?

High speed hurts less...

If i stuck an aeroplane on a giant treadmill that would spin 150mph would the plain take off

DONT START

 

[2scoops0406]

No, no lift.

 

[BOB D.O.L.E]

No, no lift.

And if i stuck 2 giant air dryers facing it blowing wing at 100mph would it take off.

No. it would get blown off the tread mill.


If the 'hair dryers' could push air fast enough over the wing so as to produce more lift than the aircraft weighs, then it would be capable of straight and level flight. However, lift only serves to counteract the weight of the aircraft. In a correctly trimmed a/c, a steady airflow over the wings will not make it rise. Manipulation of the control surfaces (Ailerons, elevators and rudder) is required to change the attitude of the aerofoil section.

Unfortunately, Bob, unless the 'hair dryer' is consistently directing its airflow within 5degrees of the aerofoil's chord line (with appropriate low-speed configuration, of course!), the wing will simply stall as the oblique angle of attack to the leading edge will create too much turbulence over a greater % of the lift surface than is necessary to counteract the a/c's weight.


ye cannae change the laws o' physics, laws o' physics ... Ji... er ... Bob.

OK clever cloggs and what about light speed, if light can travel at a speed it does with no effort how can we harvest the energy of light speed, in a way light speed is similar to sound speed but slower but sound can be used as an energy, How much light energy would we need to power a space ship i have the answer but im trying to get it pantanted.

 

[Thermo]

if it travels at light speed and you turn on the headlights what would happen?

 

[corgiman]

they to would be at lightspeed its relative

 

[ricicle]

If the spacecraft went backwards at the speed of light then the headlights would not appear to be on

You wouldn't see the spacecraft. You wouldn't know there was a spacecraft there. In fact it wouldnt be there, it'd be millions of miles away by the time you thought that there was a spacecraft there.
