A 2.3-kg sphere S is being moved in a vertical plane by a robotic arm. When the angle 0 is 28°, the angular velocity of the arm about a horizontal axis through O is 57 deg/s clockwise and its angular acceleration is 187 deg/s2 counterclockwise. In addition, the hydraulic element is being shortened at the constant rate of 580 mm/s. Determine the necessary minimum gripping force P if the coefficient of static friction between the sphere and the gripping surfaces is 0.56. Compare P with the minimum gripping force P, required to hold the sphere in static equilibrium in the 28° position. 1.4 m 8 Answers: P= Ps= 24.85 22.56 N N
