High pressure Pressure

AI Thread Summary

An inflated bicycle tyre at sea level has an internal pressure of 600kPa, significantly higher than the atmospheric pressure of 101kPa. The difference in pressure creates a net force that keeps the tyre intact. The forces acting on a small part of the tyre include the internal pressure pushing outward and the atmospheric pressure pushing inward. The structural integrity of the tyre material also plays a crucial role in preventing bursting. Overall, the combination of pressure dynamics and material strength ensures the tyre remains safe under normal conditions.

Homework Statement

At sea level, an inflated bicycle tyre has an internal pressure of 600kPa. The atmospheric pressure is 101kPa at sea level. (1 bar = 100kPa). The question is: why won't the tyre burst?

There is more pressure in the tyre, thus more force?

Hey,
On the free body diagram of a small part of tyre, what forces seem to be acting ?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
