1 A worker seated at a table performs a REACH. The sought-after object is jumbled with other objects in a tote pan, and the distance of the reach is 18in. Determine the MTM-1 symbol and normal time in TMUs for this motion element. 2 An assembly worker standing at a workbench performs a MOVE. The object being moved weighs 10lb. It is moved to an exact location a distance of 20in. Determine the MTM- 1 symbol and normal time in TMUs for this motion element. 3 An office worker sitting at a desk performs a MOVE. The moved object is a file weighing less than 1lb. The distance is an approximate location 14in. away from the starting point. Determine the MTM-1 symbol and normal time in TMUs for this motion element. 4 A mechanic performs two POSITION elements in sequence. The first requires an alignment along longitudinal axes of the objects, and the second requires an orientation of their rotational axes. Both elements can be classified as close fits with no symmetry, and the objects are easy to handle. (a) Determine the MTM-1 symbols and normal times in TMUs for these motion elements. (b) What is the total time for both elements in seconds? 11 Develop the activity sequence model and determine the normal time for the following work activity: A clerk walks 8 steps, bends and picks up a file folder from the floor, places it on the counter within reach at that location, and then returns to her original location. 12 Develop the activity sequence model or models and determine the normal time for the following work activity: An assembly worker obtains 4 bolts in one hand from a bin located 10 in. away on his worktable and puts one bolt each into four holes in the bracket within easy reach in front of him. 13 Develop the activity sequence model and determine the normal time for the following work activity: A machinist standing in front of his milling machine grasps the waist level feed lever on the machine, and rotates the lever 1 crank to engage the feed. The process time to mill the part is 50sec. There is no alignment and no action by the worker at the end of the process time. 16 Develop the activity sequence model and determine the normal time for the following work activity: A worker walks three steps, picks up a screw from his worktable, walks back to his initial location, positions the screw into a threaded hole, and turns it 5 spins with his fingers. 17 Develop the activity sequence model and determine the normal time for the following work activity: A worker picks up a screwdriver within reach from his worktable, positions it onto the head of a screw, fastens the screw with 6 turns, and lays the screwdriver aside
