How to find out contact time of 2 Carrom men in carrom board game?

AI Thread Summary
To find the contact time of two Carrom men during a game, one can experimentally measure it by recording the sound of the impact with a microphone and analyzing the waveform for duration. The discussion emphasizes that while experimental methods are suggested, there is a query about the existence of a mathematical approach for this calculation. The coefficient of restitution and pre-impact velocities are known variables that may factor into such calculations. However, the conversation leans towards practical experimentation as the preferred method. Ultimately, determining contact time remains a challenge that may not have a straightforward mathematical solution.

How to find out contact time of 2 Carrom men in carrom board game?

I am trying to develop a game of carrom board.
For this i want to know how to find contact time if Co-efficient of restitution and velocities before contact is known?

Suggest you determine it experimentally. Aim one piece at another, record the sound of the impact with a microphone, then look at the waveform to see how long it lasted.

Is there not any mathematical approach?
 

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'

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...
