An experimental set up can be easily made to rotate a disk. We can apply pressure below the disk to stretch it. But I do not understand how I can supply the heat to the disk.
Good day.
1. You can make as ten drive to feeding electric current it is heated.
2. Fix the two tenami disc, then it will warm them.
Vadum.
Santosh,
You can use a circular electric heating element (very cheap and come in different power output ratings) and mount it as close as possible to the rotating disk to apply radiative heat to the disk surface.
What is the disk made of and how much stretching do you have ?
I also think Infrared heaters would be useful, but heating effect depends on the surface characteristics of the aluminium disk (emissivity). Check this link for a wide range of Infrared heaters. They also have an agent in Chennai.
