This set of Industrial Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Recording Techniques – Set 2”.
1. Which of the following recording techniques is used for the method study of a single operator handling two or more machines?
a) Flow diagram
b) Operation process chart
c) Two hand process chart
d) Multiple activity chart
View Answer
Explanation: Multiple activities chart is used to record the activities of a group of workers or a single operator handling two or more machines. A common time scale is used to represent all the activities performed at a given instant of time.
2. Which of the following process chart doesn’t record the time?
a) Man-Machine chart
b) LH-RH chart
c) Flow process chart
d) Two hand process chart
View Answer
Explanation: Two hand process chart involves details regarding the activities of both left and right hand of the operator. This chart doesn’t employ a time scale whereas Man-Machine chart, LH-RH chart, flow process chart uses a time scale.
3. Which of the following process chart is used to record and represent the activities of more than one operator?
a) Man-Machine chart
b) LH-RH chart
c) Flow process chart
d) Gang chart
View Answer
Explanation: Gang chart is used to record the activities of more than one operator at a time. It has the number of operators defined in the chart whereas a multiple activity chart has only one operator or indicate a group of workers as one.
4. Which of the following recording techniques can record the curvilinear path of movements of worker?
a) Chrono cycle graph
b) Flow diagram
c) Flow process chart
d) String diagram
View Answer
Explanation: Chrono cycle graph uses a photographic plate to trace the path of movement of workers. A series of pear-shaped dots indicate the path of movement. A light is attached to the operator limbs which are exposed to a photographic plate.
5. Which of the following techniques employ a stereoscopic camera?
a) Chrono cycle graph
b) Flow diagram
c) Cycle graph
d) String diagram
View Answer
Explanation: Cycle graph is used to study the curvilinear movement of the worker. It is introduced by Gilbreth. He used a stereoscopic camera to study the path of movement of the worker.
6. Which of the following techniques employ a photographic plate?
a) Chrono cycle graph
b) Flow diagram
c) Cycle graph
d) String diagram
View Answer
Explanation: Chrono cycle graph uses a photographic plate to trace the path of movement of workers. A series of pear-shaped dots indicate the path of movement. A light is attached to the operator limbs which are exposed to a photographic plate.
7. Which of the following techniques uses pear-shaped dots to represent the path of movements?
a) Chrono cycle graph
b) Flow diagram
c) Cycle graph
d) String diagram
View Answer
Explanation: Chrono cycle graph uses a photographic plate to trace the path of movement of workers. A series of pear-shaped dots indicate the path of movement. A light is attached to the operator limbs which are exposed to a photographic plate. The fine end indicates the direction of movement.
