Question 2 10 pts 2. An industrial robot must lift with its mechanical gripper a weight of 20 pounds. During its operation the part is accelerated in the horizontal direction with respect to the to the contact surfaces of the fingers, and tends to pull the weight out of the gripper. If the friction coefficient is 0.2, calculate the grasping force which guarantees a safe operation of the robot. Use a safety factor of 1.5 in your design B T - V 9 A A I ? 12pt * 1 1 1 x • Paragraph = T = - O words Question 3 10 pts Avector 3:21. Kis rotated by 60 degrees the reference frame.
