Student Learning Outcomes:
After successfully completing the course, students should be able to do the following::
1. Describe an expanded view of ergonomics which encompasses prevention of soft tissue-related injuries, and maximizing work efficiency.
2. Describe ergonomic risk factors and ergonomic risk factor modifiers, and assess the impact they have on the development of cumulative trauma
disorders.
3. Differentiate between engineering and management interventions, and recommend such interventions to reduce the presence and magnitude of
ergonomic risk factors.
4. Evaluate and articulate the importance of optimizing the interface between employees and equipment/machinery, and how to optimize the interface.
5. Describe various work study methods
Pedagogy for Course Delivery:
The course pedagogy will include lectures, seminars, presentations and discussion on case studies. .

Rating: To obtain practice in rating operators performance in Card Dealing & Walking.
Man Machine Chart
(a) Prepare man machine chart for drilling two holes in a plate 10 mm. thick on a radial drilling machine.
(b) To determine standard time for drilling a hole in MS workpiece by stopwatch method.
Two handed Process Chart
(a) To draw two handed process chart for bulb holder assembly and to suggest a satisfactory layout.
(b) To find out standard time for assembly.
Left - Hand And Right - Hand Operation Chart
(a) To make left - hand and right - hand operation chart for bolts and washer assembly and
(b) Draw work place layout using principles of motion economy
Pin Board Experiment:A. To find out time requirement to fill the 30 holes with pins : by only right hand. (five cycles each), by only left hand (five cycles each) and. by using
simultaneously both hands in a symmetrical motion. (five cycles each).
B. Determine the time required to fill 30 holes in board with pins when two boards are : together (Condition A) , 30 cm apart (Condition B ) and 60 cm
apart (Condition C).
C. Determine the no. of pin boards that could be filled in a 8 hour day under each of these three conditions. Assume that an operator could maintain the
pace in the experiment and that no fatigue or delay Allowances are made.
D. Calculate in % how much more time was required to fill the pin board under condition B than A ,under condition C than A.
E. Compute the total distance in feet through which the two hands would move in filling 1000 pin board under each of these conditions.
F. Calculate in % how much further the hands would move under condition B than A, under condition C than A.
6. Process Chart and Flow Diagram
To prepare a process - chart and flow diagram for filling petrol in a scooter at a petrol pump.
7. To study with reference to the bulb holder assembly operation the following aspects : Learning effect, Sequence of operation, Preparation of 2-H
process
chart, Computing cycle time.
8. To determine the normal working area, max. working area, height for a normal man (i) for the assy. of pins in a box (ii) For the assembly of Nuts,
bolts and washers.
9. To study the operator’s performance under different working conditions (light, temp., sound, atmosphere etc.)
