TOPIC 3: Work Study

Work Study is a systematic approach to _________ and improving work processes

The Following Explain Work Study EXCEPT

• Method Study

• identify and eliminate unnecessary or inefficient motions

• determine the most efficient way to perform a task

• Work Replacement

PRINCIPLES OF MOTION ECONOMY is the study of how to INCREASE the amount of unnecessary motion or movement in a particular task or process, with the goal of increasing efficiency and productivity

• TRUE

• FALSE

Classification 3 of Hand and Arm Motions

• Finger motions only

• Finger, wrist and forearm motions

• Finger, wrist, forearm and upper arm motions

• Finger, wrist, forearm, upper arm and shoulder motions

PRINCIPLE 9 :The method should achieve a ______ rhythm of the motions involved

Both hands should be fully utilized

• First five principle, is the use of two hands and allocation of work between them

• The next five principle of motion economy attempt to utilize the laws of physics to assist the use of the hands and arms while working

• The two remaining human body principles of motion economy are recommendations for using body members other than the hands and arms

• NONE OF THE ANSWER

• NONE OF THE ANSWER

Students perform a manual assembly of a simple product (e.g. ballpoint pen, small electrical plug, or fastener set) using a pre-arranged, visually optimized workstation.

• Minimize eye focus and eye travel activities

• Momentum should be used to facilitate the task wherever possible

• The method should take advantage of gravity instead of opposing it

• The two hands should begin and end their motions at the same time
