/A

P
A homogeneous ring of radius r=0.16 m is suspended
from a peg in a vertically downwards uniform
gravitational field with g=9.80 m/s?, and loaded by a
force P as shown using a ring-fixed massless
inextensible chord. The coefficient of static friction
between the peg and the ring is u=0.31. If a force
P=10.2 N is to be supported without slip at the peg-
ring contact, calculate the minimum value of the
weight (in N) of the ring (correct to 1 decimal place).
