Hi all,
This is not exactly a homework question, more like for my own safety
So I have a project going on and I need to use an angle grinder without the safety guard which will be enclosed in a box (made from plastic most probably).
So I decided to check if the plastic box would be able to withstand the impact of the cutting disk (6'') should it break.
I decided to assume a worst case scenario where the whole disk comes off at 12000rpm.
I am assuming it has a mass of about 50g.
After converting this to angular velocity I got 1256 rad/s
I was considering F=ma where a=r⍺
⍺= change in angular velocity/ change in time.
Now this is where I got stuck, should I consider a change of 1256 rad/s in 1s?
thus having an angular acceleration of 1256 rad/s^2?
Also as for the radius, should I consider the distance which the disk will need to travel until it hits the box?
Thanks a lot
