Basically , I have two rods of 1cm diameter and 5 cm height. One of the rods is fabricated in such a way that a helical thread is created throughout the rod with a helix angle of 60° . Other rod is fabricated in such a way that the surface is diamond grit knurled throughout.
So this is done to increase the surface area compared to the smooth rod.
My question is that I want to find the surface area of each of the rods .
I hope someone could help me with this.
Thank you so much.
