Maximizing Acceleration in Circular Motion: Understanding Loop Dynamics

AI Thread Summary
In circular motion, the maximum acceleration occurs at the bottom of a loop due to the combined effects of centripetal force and gravity. For a vertical loop, the particle must exert additional upward thrust to counteract gravitational force, resulting in increased acceleration. This principle explains why objects, such as a bag swung vertically, experience the greatest tension at the bottom of the swing, making them more likely to break. Understanding these dynamics is crucial for analyzing forces in various loop designs. Acceleration in circular motion is fundamentally influenced by the loop's orientation and the forces acting on the particle.

If a particle moves inside a loop then when is it's acceleration at a maximum? ie in a loop the loop

What kind of loop? If it's a circle, the acceleration is constant.

Do you mean In a loop-d-loop? like a plane flying in a vertical circle?
In this case, there is also gravity to consider. The acceleration toward the centre of the circle must always be the same, so when the plane is at the bottom of the loop, it must create more upward thrust to cancel out the force due to gravity.
This is why if you swing a bag round (vertically), it is most likely to break at the bottom of the swing, since the tension is greatest at this point.
 

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?
