ME 360 Midterm: ME 360 Alabama Test2 Fall02
Document Summary
When you turn in this part of the test you will get the second part which allows a page of handwritten formulas. Over: measurements of the weight of 100 manhole covers give an average weight of 14. 73 lb with a standard deviation of 0. 26 lb. What is the uncertainty in the average weight at the 95% confidence level: you are given two capacitors: ca= 0. 0022 f and cb= 470 pf. What are the series (cs) and parallel (cp) capacitances: the first natural frequency of a vibrating beam is given by the formula, 3 simplified formula for calculating the uncertainty, u / . Closed book, closed notes, one 8. 5x11 inch hand-written formula sheet allowed. Work the problem in the space provided below each problem. Eight measurements of resistance (in k ) are listed below. Determine the mean value and the precision uncertainty for the mean at a 95% confidence level. A fluke 75 dmm was used to measure the resistances.
