Hello to all,
Im new here, just found the site and wishing I had stumbled across this a few months back when I started my Electrical engineering course.
I hope this is in the correct section, I did read through where to put this but apologies if I have placed this in the wrong section...
I have a distinction level question in my science assignment which is causing me some headache, any help, guidance or pointers in the right direction would be much appreciated! I am not looking for answers but looking for ways too those answers if possible..
Q) A solid flat disc is rotating horizontally. If a mass of 2KG is placed 0.15M from the centre of rotation and assuming a coefficient of friction of 0.3, determine;
i)The maximum angular velocity that the disc can be rotated at without the block moving
ii)The linear velocity of the block if the angular velocity in (i) is exceeded.
iii)If the block mass was increased to 4KG what effects would this have on the max angular veolcity calculated in (i)...
I have some idea of linear and angular motion but we only briefly touched on combining the two into questions like these, we were told to "Have a go" at this question if we could, problem of course is that if you can't do it you can't hit the distinction grade...With a few pointers i think i could work this out, can anyone help??
many thanks, hope to see you in the forums
