The purpose of work measurement is to determine the time it ought to take to do a job. The problem is in the definition of "ought to." Work measurement analyst define this as the time it should take an experienced and well-trained operator to perform the job in a specific and well-defined method at a speed that can be maintained all day‚ day after day‚ without undue fatigue. This time‚ called standard time‚ can be divided into several parts: the actual elements used to perform the job; the rating

Chapter 13 AC MEASUREMENT This chapter explains rectification for measurement and rectifying instruments. Knowledge of the circuit principles will help you use these instruments properly and measurements alternating current correctly. One of the most common and economical methods for measuring alternating currents is to rectify these currents and read the resultant DC on an analog or digital volt-ohm meter (VOM). You need to take many considerations into account when using rectification: what

Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count

Physiological measurements Body Temperature: This is the body ability of the body to generate and get rid of heat. It is measured via the mouth‚ ear‚ forehead and armpit. The hypothalamus in the brain regulates body temperature. Body temperature is maintained by constant burning of fuel in cells. It burns carbohydrates and fat. This constant burning of fuel is a chemical reaction of carbohydrates/fat with oxygen. This will be converted to CO2‚ water and heat and it is due to that heat the body

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy
