which collision of marbles is more elastic, steel on steel or steel on glass?
Steel on steel refers to two pieces of steel rubbing against each other, while steel on glass refers to a piece of steel rubbing against a piece of glass. The main difference is the material being rubbed against, which can affect the friction and wear properties.
This depends on the specific application and the type of steel and glass being used. Generally, steel on steel tends to be more durable because both materials are harder and have a lower coefficient of friction compared to steel on glass.
Both combinations can cause damage over time due to friction and wear. However, steel on glass is more likely to cause damage to the glass due to its lower hardness compared to steel.
The surface finish of both materials can greatly impact the friction between them. Rougher surfaces tend to have higher friction due to increased contact area, while smoother surfaces have lower friction due to reduced contact area. In general, a smoother surface finish on both materials will result in lower friction and wear.
Yes, lubrication can greatly reduce friction and wear between steel and glass. It acts as a barrier between the two materials, reducing the direct contact and allowing for smoother movement. However, the type of lubricant used should be compatible with both steel and glass to avoid any damage to either material.
