3. The member OA rotates in vertical plane about a horizontal axis through O with a constant counter clockwise velocity w=3 rad/s. As it passes the position 0=0, a small mass m is placed upon it at a radial distance r=0.5 m. If the mass is observed to slip at 0=37°, find the coefficient of friction between the mass and the member. Answer: μk = 0.1875 Solution Ө
