# Physics

The system shown in the ﬁgure is in equilibrium. A 15 kg mass is on the table. A string
attached to the knot and the ceiling makes an
angle of 54◦
with the horizontal. The coeﬃcient of the static friction between the 15 kg
mass and the surface on which it rests is 0.4
What is the largest mass m can have and
still preserve the equilibrium? The acceleration of gravity is 9.8 m/s^2
Help is appreciated guys
