QUESTION 2 Thermocouples are devices used to measure temperature of a given sample or the surrounding medium. These devices feature a "bead", which has a spherical shape, and produces voltage upon change in temperature. For an engineering application at a pharmaceutical company, thermocouple devices are being tested for their responsiveness, i.e. how fast it can detect temperature changes in the environment (surrounding air). The engineers at this company have specified design constraints for an ideal thermocouple: it must detect temperature changes no later than 1.5 minute, and the reported temperature value must be reasonably correct: at most %3 difference between measured and actual temperature values is allowed. Four thermocouples from different vendors are being tested. Relevant properties of these devices are listed below: Thermal conductivity Density 36 W/m*K 36 W/m*K 42 W/m*K 33 W/m*K Specific Heat 140 kJ/kg*K 120 kJ/kg*K 150 kJ/kg*K 160 kJ/kg*K Device Bead Diameter…

Pressurized eyes Our eyes need a certain amount of internal pressure in order to work properly, with the normal range being between 10 and 20 mm of mercury. The pressure is determined by a balance between the fluid entering and leaving the eye. If the pressure is above the normal level, damage may occur to the optic nerve where it leaves the eye, leading to a loss of the visual field termed glaucoma. Measurement of the pressure within the eye can be done by several different noninvasive types of instruments, all of which measure the slight deformation of the eyeball when a force is put on it. Some methods use a physical probe that makes contact with the front of the eye, applies a known force, and measures the deformation. One non-contact method uses a calibrated “puff” of air that is blown against the eye. The stagnation pressure resulting from the air blowing against the eyeball causes a slight deformation, the magnitude of which is correlated with the pressure within the eyeball.…

Stiffness is the property that enables a material to withstand high stress without great strain. It is a resistance to any sort of deformation and is a function of the modulus of elasticity, E, of the material. True False   There are currently two (2) systems of units used in engineering practice in the United States; they are the U.S. Customary System, also referred to as the English System, and the International System or the SI System.

Basic Manufacturing Process with 2 Job Types + Inspection Time between job arrivals at a machining station is exponentially distributed with mean 4.4 minutes. There are 2 types of jobs to be processed 30% of which is Type 1 and, 70% are of Type 2. Processing times are exponentially distributed. Mean processing time for Type 1 is 4.8 minutes, for Type 2 it is 2.5 minutes. After the job is processed, they go through an inspection process with one single inspector and an inspection time with triangular distribution (1,2,3.5). Inspector decides whether the part is good enough, scrap or should be reworked. 80% of the parts produced is good, 10 % is scrap and the rest needs rework. Rework is done by the same manufacturing machine. The priority among the parts will be Part1 first, part2 second and reworks of both type comes later. Rework time is normally distributed with mean 2 minutes and 0,2 std dev. Simulate the system for one 8-hour day.

Chapter 3: 13. What type of geometric tolerance has no datum features? 14. A theoretically exact dimension is called a 15. The feature symbol specifies that a group of two or more interrupted features of size are to be considered one single feature of size. 16. For an individual regular feature of size, no element of the feature shall extend beyond the maximum material condition boundary (envelope) of perfect form. This statement is the essence of 17. What is the name of the symbol used to identify physical features of a part as a datum feature and must not be applied to centerlines, center planes, or axes? 18. The is the condition in which a feature of size contains the maximum amount of material within the stated limits of size. 19. The total positional tolerance equals the sum of the tolerance and the tolerance.

Industrial engineering question please solve fast

You’re testing a system that involves a fan, water pump, and compressor. The components are turned ON in sequence and sensor readings are taken, as per a written protocol that you’re following. The system is running as expected after the fan and water pump are turned ON. However, when you turn ON the compressor, it runs for about thirty seconds then stops, consistently. Swapping out the compressor for a different one seems to solve the problem. What could have been the issue with the bad compressor?

Question 2 In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity and are subject to uncertainty. Uncertainty means the range of possible values within which the true value of the measurement lies. (a) Determine FIVE (5) sources of uncertainties in measurement and explain how to reduce the uncertainties. (b) Determine FIVE important measurements of uncertainty for precision engineering.

A. A student establishes the time constant of a temperature sensor by first holding it immersed in hot water and then suddenly removing it and holding it immersed in cold water. Several other students perform the same test with similar sensors. Overall, their results are inconsistent, with estimated time constants differing by as much as a factor of 1.2. Offer suggestions about why this might happen. Hint: Try this yourself and think about control of test conditions. B. Which would you expect to be better suited to measure a time-dependent temperature, a thermal sensor (e.g., a thermocouple) having a small diameter spherical bead or one having a large diameter spherical bead? Why?

PLTW Engineering Activity 3.8 Precision and Accuracy of Measurement Introduction This concept of random and systematic errors is related to the precision and accuracy of measurements. Precision characterizes the system's probability of providing the same result every time a sample is measured (related to random error). Accuracy characterizes the system's ability to provide a mean close to the true value when a sample is measured many times (related to systematic error). We can determine the precision of a measurement instrument by making repeated measurements of the same sample and calculating the standard deviation of those measurements. However, we will not be able to correct any single measurement due to a low precision instrument. Simply stated, the effects of random uncertainties can be reduced by repeated measurement, but it is not possible to correct for random errors. We can determine the accuracy of a measurement instrument by comparing the experimental mean of a large number…
