Write a list of the therbligs that comprise this motion sequence and label each basic motion with a brief descriptio
3. A plumber, kneeling on the floor next to the sink, reached for the monkey wrench in his toolbox, pushing around a few other tools before grasping the wrench and picking it up. He then moved it to the pipe beneath the sink, positioned it into the pipe fitting, and turned the fitting one-third of a rotation to loosen it. Once loose, he put down the wrench and continued turning by hand. Four rotations were required before the fitting was free of the mating pipe threads, during which he had to grasp and regrasp the fitting ten times due to the limited rotation ability of his own wrist. Write a list of the therbligs that comprise this motion sequence and label each basic motion with a brief description.
