The member OA rotates about a horizontal axis through O with a constant counterclockwise angular velocity

Question:

The member OA rotates about a horizontal axis through O with a constant counterclockwise angular velocity ω = 3 rad /sec. As it passes the position θ = 0, a small block of mass m is placed on it at a radial distance r = 18 in. If the block is observed to slip at θ = 50°, determine the coefficient of static friction μs between the block and the member.
