Question

On the smooth quarter
block, a particle 15
rest.
ne smooth quarter circular surface of the
ck, a particle is released from the state of
The block has mass M and
the partide has mass m.
he coefficient of friction between the block and
the ground is u.
e that the normal reaction acting on the particle after it has rotated by an
angle measured with the horizontal, is equal to
N = 3mg sino
After that prove that the friction force needed from the ground to keep the block
in the state of rest is
F,
3mg sino coso
Thereafter, prove that the normal reaction acting on the block from the ground
is
N, = Mg + 3mg (sino)?
Finally using trigonomctry and the condition that requirement must be less than
or equal to the maximum available show that
>
(1+2K)- 12 , where K = M/3m
4K(1 +K)​
