Mechanics - Cylinders, springs and rough inclined plane
In summary, the conversation discusses the lack of friction in a scenario where a spring is present. The concept of taking moments about the centre of the cylinder is mentioned as a hint to understand why there would be no friction. The participants also question whether there would be both friction and spring force, but the solution states that there would only be a spring force.

Friction is a reaction force, if the spring is there then there would be no need for it (possibly?)

i just need to know why solution says there will be no friction

shouldn't there be both friction and spring force and friction?

yes, take moments about the centre of the cylinder, and you'll find out!

1. What is the relationship between the pressure and volume of a gas in a cylinder?
The relationship between pressure and volume in a gas cylinder is known as Boyle's Law. It states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means that as the volume of a gas in a cylinder decreases, the pressure inside the cylinder increases, and vice versa.
2. How does Hooke's Law apply to springs?
Hooke's Law states that the force applied to a spring is directly proportional to the amount that the spring stretches or compresses. This means that the more force is applied to a spring, the more it will stretch or compress, and the less force is applied, the less it will stretch or compress.
3. What is the significance of the coefficient of friction in an inclined plane?
The coefficient of friction is a measure of how rough or smooth the surface of an inclined plane is. It determines the amount of resistance that a body will experience while sliding down the inclined plane. A higher coefficient of friction means a rougher surface and more resistance, while a lower coefficient of friction indicates a smoother surface and less resistance.
4. How does the angle of inclination affect the force required to push an object up an inclined plane?
The angle of inclination, or the angle at which the inclined plane is tilted, affects the force required to push an object up the inclined plane. As the angle increases, the force required to push the object up also increases. This is because the steeper the incline, the more the force of gravity is acting against the motion of the object.
5. Can the energy of a system be conserved when using a rough inclined plane?
No, the energy of a system cannot be conserved when using a rough inclined plane. This is because the friction between the surface of the inclined plane and the object causes the energy to be converted into heat and sound, resulting in a loss of energy. This means that the object will not have the same amount of energy at the top of the inclined plane as it did at the bottom.
