Rolling Cylinder Pair, Metal and Plastic Set
$128.00(Ex GST)
- Rolling cylinder pair, one plastic and one metal, classic incline rolling mechanics demonstration set.
- Same size and same total mass, controlled comparison removes size and mass as variables.
- Different internal mass distribution causes different rolling behaviour down the same slope conditions.
- Demonstrates rotational motion effects from mass distribution, useful for classroom discussion and timing runs.
- Heavy cylinders and plastic damage risk, handle carefully and avoid dropping during student practicals.
- Description
Description
These rolling cylinders are supplied as a matched pair made from plastic and metal for classic mechanics demonstrations. Because the cylinders are heavy and plastic can be damaged, they should be handled carefully and not dropped onto the floor during student practical work.
Although the cylinders are the same size and have the same total mass, they have different mass distribution. This causes them to behave differently when rolled down a slope, making them suitable for demonstrating how mass distribution affects rolling motion under identical external conditions.
FAQs
Q: What is included in the set?
A: A pair of rolling cylinders, one plastic and one metal.
Q: Why do they behave differently on a slope?
A: They have different mass distribution, even though size and total mass are the same.
Q: Are the cylinders the same size and mass?
A: Yes, identical size and identical total mass are stated.
Q: What precautions should be taken?
A: Handle carefully and avoid dropping, as the cylinders are heavy and plastic can be damaged.
Q: What concept does this demonstrate?
A: The effect of mass distribution on rolling motion down an incline.
