Hello all! I am new to this forum, although I browse around here often, I recently took the plunge to make an account. I finished my college a few years ago and want to move back into schooling for uni so I need to do some courses over the next few months. please be patient, sometimes I forget the simplest of things. for instance..
I am not sure if this is a trick question, I have 2 boxes of different mass but same static friction... if I am not mistaken, I believe both boxes will begin to slide at the same angle, regardless of weight..
2 boxes, 10 KG and 20 KG with a coefficient of static friction of 0.4. calculate the angle each box begins to slide
I would assume neither of the masses are taken into account for this so.. I did
∅=arctan(µs)
∅=tan^(-1) (0.4)
∅=21.8°
therefore each box will begin to slide at any angle ABOVE 21.8 right ? I would assume the 21.8 is the MAX angle before they begin to slide. or am I missing something important ?
