Underwriters Laboratory (UL) D. Occupational Safety and Health Administration (OSHA)Explanation / Answer
16 -D, all thr Ac/Dc servo motors are used in eletrical drives
17-A, only hydraulic system requires tank ,fluid and pump
18- D, all the three parameters effect the working enevelope of the robotic arm
19 -D, a robotic arm which had sperocal configuration can move and stop in x,y and z axis
