    Em Pressure Wave
AI Thread Summary
Creating a pressure wave from electromagnetic radiation emanating from a spherical surface is theoretically possible, but it relies on the principles of photon pressure, which depends on photon energy and intensity. In inertial confinement fusion, the pressure is generated not directly from photon pressure but from the ablation of an outer layer due to rapid heating and energy deposition. This process creates an impulse on the fuel target, facilitating the desired pressure wave. The discussion emphasizes that the method must avoid using explosives for implosion. Overall, the focus is on the mechanics of generating pressure waves through electromagnetic means without explosive methods.

Hello, is it possible to create a pressure wave from any form of electromagnetic radiation that travels inward to a central point emanating from a spherical surface.

Also, the pressure wave must not be produced from explosives that are imploding.

You are describing the attempts at laser induced fusion.

The pressure due to photons depends on the energy of the photons and the intensity (number of photons) or flux (number of photons/unit area).

In the inertial confinement scheme using lasers (and even electron beams), it is not the pressure from photons, but the ablation of an outer layer as a consequence of rapid heating and energy deposition that provides the pressure (impulse) on the fuel target.
 
Thanks guys!
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
