i have to design an actuation system which will change the angle with which the power is transmitted through a motor,the range of angle is about,--35 to +35,w.r.t to the vertical,what should i use,a u joint or a velocity joint?there is a predefined load on the shaft(bending + torsional),what...
thanx, for the reply, I guess pressure is the key, once it is disturbed by an external force , more volume of air will try to compensate its lift,creating a suction of air,and letting it escape faster, hence there will be less convergence of velocity into dynamic pressure thus the hovercraft...
thanx for the reply flyboy, but I wanted to know wether a skimmer if lifted with some external force, such that partly the weight is divided in between air film and a force such that both of them are in perfect equilibrium, then ,will the hovercraft still be able to produce a lift even if the...
I was wondering what will happen to a hovercraft which is designed for a given air film thickness, is. slightly lifted above its air film, will the hovercraft start behaving like an helicopter, which uses the action- reation phenomenon to keep itself in the air or it will still continue to slip...
i wonder what happens to a photon once it comes to rest and its rest mass becomes zero, such that no gravity can act on it, so should the photon have escaped , just after it was sucked?
First of all there is a difference between the rest mass and the relativistic MASS, in general relativity an object which moves with a velocity shall experience an in crease in its mass. Similarly the rest mass of a photon is zero but yet its energy provides its mass (m=hf/c2).The second thing...
I was wondering that what will happen to a car which has a negative camber angle of over 45 degrees, will it make impossible to even move or it is possible if we design special tires for the same..? i know it will be almost impossible to steer such a vehicle but i want to know what is the...
hey i had a bizarre thought, what if there is a road made with a very smooth friction less surface and a normal asphalt road, arranged alternatively, such that , half the time spend by the tire in one rotation is placed on the smooth side and the other half on the rough side, such that the tire...
