Doppler shift source velocity components

AI Thread Summary
The discussion focuses on the Doppler effect when the observer and source are not moving in a straight line. It emphasizes that only the velocity component parallel to the wave's propagation direction should be considered in the Doppler effect equation. The conversation highlights the importance of accounting for the wave's travel direction and the receiver's position at the time of pulse reception, especially if the receiver is accelerating. Proper mathematical setup is crucial for accurately leading a moving target. Understanding these components is essential for applying the Doppler effect correctly in complex scenarios.

how does the doppler effect work when the observer and source are not moving in a straight line, what do we take in as the velocity of the observer and the source in the doppler effect equation?

What do you think?

Given the physics of what's going on there's only one plausible answer as far as I can see.
 
is it the velocity component that is parallel to the direction of the propagation of the wave?
 
Correct. You need to take care about what direction the wave is traveling because where the receiver is when it receives a pulse is not where it was when it was emitted (which can get messy if the receiver is accelerating). As long as you remember about leading a moving target when you set up your maths, you're fine.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

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...

Thread 'Newton's first law?'

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'

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...
