Principles of motion economy ppt
Motion economy is the study of how to design and optimize movement in order to save energy, improve efficiency, and reduce fatigue. It is an important concept in a wide range of fields, including industrial engineering, ergonomics, and sports science. The principles of motion economy can be applied to many different types of tasks and activities, from manufacturing processes to athletic performance.
One key principle of motion economy is the idea of minimizing unnecessary movement. This means finding ways to eliminate or reduce any extraneous or unnecessary motion that does not contribute directly to the task at hand. For example, in a manufacturing process, this might involve designing tools or equipment that allow workers to perform tasks with minimal hand or arm movement, or streamlining the layout of the workstation to reduce the need for workers to walk or reach for materials.
Another important principle of motion economy is the concept of using the most efficient movement patterns possible. This involves identifying the most effective and efficient way to perform a task, and then training or practicing that movement pattern in order to improve performance and reduce the risk of injury. For example, in sports, this might involve analyzing an athlete's technique and identifying areas where they can improve their form in order to move more efficiently and conserve energy.
In addition to minimizing unnecessary movement and using efficient movement patterns, there are several other principles of motion economy that can be applied in different situations. These include using the right tools and equipment for the task, maintaining good posture and body alignment, and using proper lifting techniques to prevent strain and injury.
Overall, the principles of motion economy are an important part of optimizing movement and improving efficiency in a wide range of tasks and activities. By understanding and applying these principles, individuals and organizations can save energy, reduce fatigue, and improve performance and productivity.

Predetermined Motion Time System PMTS PMTS is a work measurement technique where by times, established for basic human motions classified according to the nature of the motion and the conditions under which it is made are used to build up the time for a job at a defined level of performance. They may be grouped under three headings Use of the human body. Continuous movements that are smooth and curved are superior to jerky straight-line movements, which involve sudden changes of direction and loss of momentum. Tools, materials and controls should be located close to the point of uses. EXAMPLE ON USE OF HUMAN BODY USING MOTION PICTURE FILM Print of motion picture film showing eye and hand motions of the operator assembling small parts. Greater fatigue is caused when only one hand works, while the other one is idle. It shows the left hand covering the maximum working area and the right hand covering the normal working area.
What are the Basic Principles of Motion Economy?
. The other hand is relegated to a minor role, such as holding the object, while the preferred hand works on it. Momentum should employed to assist the worker whenever possible, and it should be reduced to minimum if it has to be overcome by muscular effort. Motions involving fingers, wrist, and forearm. PRINCIPLE OF MOTION ECONOMY RELATED TO DESIGN OF EQUIPMENT - EXAMPLE 28. Work should be arranged to permit an easy and naturalrhythm wherever possible.
Motions of the arms should be made in opposite and symmetrical directions and should be made. The height of the work place and the chair should preferably by arranged so that alternate sitting and standing at work are easily possible. The application of this principle, enabling both hands work at similar tasks simultaneously, leads to a better design of jigs, fixtures and duplication of tools. Hand and body motions should be confined to thelowest classification with which it is possible toper form the work sat isfactorily. Classification of movements Image Source: thyblackman.

(DOC) Applications of Principles of Motion Economy
After the assembly has been madeat POA, it is dropped into the cut portion in the work table PDA Place for dropping POAassemblies from where the assembly isdelivered at its destination with the help of aconveyer. Handles such as those on cranks and large screwdrivers should be designed so as to permit as much of the surface of the hand as possible. Bins containing P-1, P-2, P-3, and P-4 and commonly employed tools CET like screw driver, plier, etc. Use of Human Body The motions of the arms should be symmetrical and simultaneous and opposite in direction. Ballistic movement are faster, easier and more accurate than restricted or controlled movements.

Design of tools and equipment. SUBDIVISIONS OF PRINCIPLES OF MOTION ECONOMY Principles of motion economy will be presented under the following three subdivisions:1 Principles of motion economy as related to the human body. Time Study Time study is a work measurement technique for recording the times and rates of working for the elements of a specified job carried out under specified conditions, and for analyzing the data so as to obtain the time necessary for carrying out the job at a defined level of performance. They were first used by Frank Gilbreth, the founder of motion study, and have been amplified by other workers, notably Professor Barnes. It may not be possible to completely balance the workload between the right and left hands, but it should be possible to avoid having both hands idle at the same time.

Materials, tools and jigs must be so positioned to eliminate undue changes of direction and to incorporate smooth, curved and continuous movements. PRINCIPLES OF MOTION ECONOMY RELATED TOARRANGEMENT OF WORKPLACE -EXAMPLE 17. Advantages of PMTS It eliminates inaccuracies associated with watch time study. BOLT AND WASHER ASSLY- IMPROVED METHOD 21. Principles Of Motion Economy A better method of doing a job is one which consume minimum of time and energy in performing limb hand, foot, legs etc motions in order to complete the job and this is possible due to economizing the use of motion. This will help in balancing the body and there will be less stress on the workers body.

Proper balance is achieved only when the movement of one hand is the mirror image of the movement of the other. Rules Concerning Human Body Both hands should be used for productive work. Motions of t he arms should be m ade in oppositeand symmetrical directions and should be m adesimultaneously. In the first picture woman is carrying bucket in one hand and her body is imbalanced where as in the second picture woman is carrying weight equally in both the hands so more body balance.

At times, it may be necessary to compromise on the principle of minimum movements in order to equitably distribute the physical load over the various muscles.
