Introduction:This is the fifth work study lab report, which will be about Motion Study (Therbligs Technique) XE "5. Motion Study (Therbligs Technique)" . First of all, Motion study is an analysis of the basic hand, arm, and body movements of workers as they perform work. As we mention, in this lab we use therbligs technique which include physical elements such as transport, grasp assembly and it refers to any activity that needs physical hands movements. Also, therbligs include mental elements such as position, search and select and it refers to any activity that needs to information process and visual effort rather than physical effort.The objectives of therbligs analysis are:Eliminate ineffective therbligs if possible; for example, eliminate the need to search for parts or tools by positioning them in a known & fixed location in the workplace.Avoid holding objects with hand – Use work holderCombine therbligs – Perform right-hand and left-hand motions simultaneouslySimplify overall method re-sequence of therbligs in the cycleReduce time for a motion, e.g., shorten distance of therbligs such as transport loadedThis report will conclude the experiment's objective, material used experiment procedure and result.The Work:The objectives of this laboratory experiment are as follows:To understand and use the therblig analysis technique for hands motion while manual assembly task and create the present therbligs list of right and lift hands while perform a simple assembly task.To learn the various symbols of therbligs that used to analysis the hands motion activities.Understand how can make improve in the therbligs symbols in order to improve the hands motion activities and create the proposed list of therbligs chart for an improved activities of right and left hands activities. In this experiment we used:Roeder Board Manipulative Aptitude Test: This board is the test that uses to measure hand, arm, finger dexterity, and speed. The board of the roeder board has four receptacles for holding washers, rods, caps, and nuts. The performance board also is comprised of a horizontal T-bar and 40 inserts arranged in a predetermined pattern. And digital stopwatch also records the time to complete a taskThe procedures of the experiment:Present Method:1. First of all, we do the Present Method we put the washer, rods, caps, and nuts randomly in one of the four receptacles of the board. 2. We start by picking up the tools sequentially and assemble it in the spots of the board, and measure the total time for each assembling cycle.3. Finally, we analyse each step the worker do while doing the assembling steps to represented in the present table that will be shown in this report.Proposed Method:1. Second, we do the Proposed Method we put the washer, rods, caps, and nuts arranged in the four receptacles of the board, also we can use the horizontal T-Bar to put the washer and nuts. 2. We start by picking up the tools sequentially and assemble it in the spots of the board, and measure the total time for each assembling cycle.3. Finally, we analyse each step the worker do while doing the assembling steps to represented in the proposed table that will be shown in this report.1243387107134Table 1. Present Method 1?00Table 1.

Also in this report we will clarify the procedure of our experiment and what we concluded after applied the motion study and work design. In this experiment we have used two different methods each one have different time depends on the procedure of the method. After we tried both methods we’ve know the benefits of motion study such as, eliminate ineffective motions if possible, simplify overall method, reduce time for each motion and to maximize efficiency. We can recognize that in any small or big project in the real life and even in industries and companies it's more useful for us to use motion study to save our time and resources. ................
