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…

I want to briefly summarize what he is talking about and what you conclude. pls very urgent

ECO 5. AUTOMOTIVE. The power an engine produces is called horsepower. In mathematical terms, one horsepower is the power needed to move 550 pounds one foot in one second, or the power needed to move 33,000 pounds one foot in one minute. Power, in physics, is defined simply as the rate of doing work. The formula below gives the horsepower at 5,252 radians per second. https://philkotse.com/toyota-corona-ior-sale-in-baguio/1991-for-sale-in-aid7017151 625T 1313 where H is the horsepower and T is the torque a. Find the inverse of the model. b. If a taxi produces a horsepower of 200, what is the torque it generates? Solve here:

What is the 95% confidence interval for each of the three measured parameters?

Two kinds of bacteria are found in a sample of tainted food. It is found that the population size of type 1, N1 and of type 2, N2 satisfy the equation dN/dt=-0.1/N1 dN/dt30.7/N2 N1 is equal to 1000 at time equal to zero, while N2 is equal to 30 at time equal to zero. Then the population sizes are equal N1 = N2 at what time? (4 decimal places)

APPLICATIONS OF FIRST ORDER DIFFERENTIAL EQUATIONS Newton’s Law of Cooling and Joint Proportions   At 4:00pm, a thermometer reading of 28 deg C is taken outside where the ambient temperature is –11 deg C. At 4:05 pm, the thermometer reads 8 deg above zero. After a while, the thermometer is returned to the room maintained at 28 deg C. At 4:12pm, the thermometer reads 15 deg C. When was the thermometer returned to the room?

In a linear spring finite element model, as per the finite element model’s sign convention, which one of the following statements is true?   Select one: a. If Fe1 is negative then the spring is under compression b. If Fe2 is negative then the spring is under tension c. If Fe1 is positive then the spring is under tension d. If Fe2 is positive then the spring is under tension

The rapid progress of engineering design and information technology has caused difficulties in analyzing system reliability. Because of the increased complexity in system reliability structure (component/subsystem interfaces), many unexpected failure modes could occur, and their behaviors are interdependent. At a system’s design and development stage, the main challenge in analyzing a complex system is the failure uncertainty introduced by the incomplete knowledge of the system. This makes it hard to decompose system reliability into subsystem/component reliability in a deterministic manner, such as series or parallel systems. As a result, some common reliability analysis tools such as fault tree (FT) and reliability block diagram (RBD) become inadequate. Do you agree, why or why not? Are there any other approaches to system reliability assessment beside these tools at the early system’s design and development stage (what are these approaches)?

Q.49 A person operates a machine that makes capacitors. He has been advised to keep the track of the percentage defectives at his work center. He knows that this type of process, they expect about 4% defectives plus or minus some chance variation. He wishes to initially construct a control chart for defectives. He has prepared ten daily samples of hundred capacitors each. Sample No. 1 2 3456 789 10 % defectives 4 3 36 195 12 4 3 ) Construct the relevent control chart. What are upper and lower control limits?
