  • Temperature effects on aluminium items

    When the temperature of aluminium is increased, the metal expands and this is called thermal expansion. One example of thermal extension is that if, for example, the temperature of a piece of aluminium alloy 6063 is -20 ̊C and its length is 2700 mm long, and it is heated to a temperature of 30 ̊C, it will subsequently be 2703 mm long due to thermal expansion.

  • Will a hole cut into a metal disk expand or shrink when

    In order to get the hole to shrink, you would need to use a material with a negative thermal expansion coefficient $\alpha < 0$, which means it gets smaller as the temperature gets higher. In that case the entire disc would shrink as it heats up. Wikipedia has an

    Instead of a circular hole, let's think of a square hole. You can get a square hole two ways, you can cut it out of a complete sheet, or you can ge.69David Zaslavski's answer is correct and complete. But I want to propose a different way to look at the problem. Think of the disc that was cut out,.38Good question! Assuming the disc is uniform and isotropic (the same in different directions), the hole will expand in the same ratio as the metal37If you worked in an auto shop, you'd know the answer already. When an axle gets stuck in a ball bearing, one way to pull it out is to heat up the b.24Im a machinist. We commonly heat holes to expand them in various applications. For example, to install bearings that demand a press fit. We use.11I think that there is an important assumption at work here. The hole will expand as long as the material is sufficiently rigid; since most things t.3I know it has been answered already.
