Please help. This problem involves finding the number of revolutions before a coin slips on a rotating disk. Thank you.
Transcribed Image Text:Q5. 3/71 from book. A small coin is placed on the horizontal surface of the rotating disk. If the
disk starts from rest and is given a constant angular acceleration 0 = a, determine an expression for
the number of revolutions n through which the disk turns before the coin slips. The coefficient of
static friction between the coin and the disk is µg.
Note 1: The only force in the horizontal plane on the coin is friction and it is this friction that
prevents slip of the coin. When the coin increases in speed, the friction force
Note 2: The coin starts to slip when the total magnitude of the horizontal friction force needed to
hold the coin in place exceeds H,N, where N is the normal reaction on the coin.
Note 3: Assume that the friction direction is not known. That is, there may be friction both in the
radial and tangential direction.
