Cutting Roller Speed Table

AI Thread Summary

The discussion centers on the speed transition of a bar on a roller table after cutting, with the rolling mill operating at 10 meters per second and the roller table at 20 meters per second. After cutting, the bar must accelerate from 10 to 20 meters per second, and the time taken for this transition is influenced by friction. A rigid connection, such as a rack and pinion, would cause the system to jam rather than allow for a smooth acceleration. Understanding the dynamics of this speed change is crucial for efficient operation. The conversation highlights the importance of considering friction and connection types in speed adjustments.

If rolling mill is running at 10 meters per second and roller table is running at 20 meters per second.
Before cutting of bar, it will move at 10 meters per second.
After cutting bar has to move with the speed of 20 meters per second on roller table.
How much time bar will take to reach to that speed?

It depends on the friction, surely. If it were a 'rack and pinion' / rigid connection, it would jam.

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 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

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?
