Therblings were an essential part of the motion and time study. This concept was developed by Frank (1883 - 1924) and his wife Lillian Gilbreth (1878-1972). Frank was a contractor and Lillian a psychologist and their combined efforts in testing and measuring efficiency resulted in the invention of a device known as the microchronometer. They used stroboscopic pictures and also motion picture cameras with a clock that enabled the worker's motions, the time taken and the conditions surrounding the job to be recorded simultaneously. They then made wire models that allowed the work task to be analysed in detail and re-designed to be performed more effectively. Hence they were able to eliminate unnecessary motions that were not perceivable by the naked eye. Thus they developed a system of 17 hand motions and each was ascribed its own symbol, colour and standard time necessary to perform it. Their secondary goal, besides enhancing efficiency, was to reduce the unnecessary fatigue experienced by workers. The term therbling comes from the couple's family name written backwards with the t and h transposed.

What are the similarities between uniform and nonuniform motion?
in uniform motion velocity not changes with time but in non uniform motion velocity changes with time.
Why is it a good idea to have a regular time of day to study?
~Its easier to study, and it will make studying feel natural. If you pick a regular "study time" every day, you'll find it easier to study. Creating a regular study time makes studying feel natural. Try to study at a time when your mind is active and ready to learn, and not at a time when you're frequently distracted or tired.

Differences between time study and motion study in scientific management?
The main points of differences are:(1)Motion Study involves the study of motions on an operation while the time study notes the time involved in carrying out each element of operation.(2)The main aim of Motion Study is to reduce wastage of time and materials scraping the unnecessary movements whereas the time study aims at fixing the standard time for carrying out a job.(3)Time study is not suitable for workers where quality is prime consideration. Motion study is suitable for all types of jobs.
