Dr. Brown has built a 94 cm pendulum and pulled the pendulum 25° from vertical and then measured the period of 30 consecutive swings. The data is shown below. How do you interpret the uncertainties involved in this data?

O The random uncertainty starts large (approximately 0.03 s) but decreases quickly until it is immeasureably small by the end of the data set. O Some systematic effect lowers the period of the pendulum by about 0.01 s in between the first and last data point. O The systematic uncertainty starts large (approximately 0.01 s) but decreases quickly until it immeasurably small by the end of the data set.
How do i find the tolerances from standard tables for H7 and s6? The answer should be: For H7 (hole) at diameter 50 mm: Upper deviation (ES): +25 µm Lower deviation (EI): 0 µm For s6 (shaft) with diameter 50 mm: Upper deviation (es): +59 µm Lower deviation (ei): +43 µm
Ten measurements are taken resulting in a standard deviation of 0.10 s.a. Determine the uncertainty in the measurement.b. If an uncertainty one fifth the value found in a. is desired how many measurementswould be required (assume that the standard deviation with this number ofmeasurements is the same as with ten measurements).

Question d and e
ham A beam of circular cross- section is subjected to pure bending moment M and the bending stresses are given by the following equation: 32 Мь ла where d is the diameter of the beam. It has been observed that the diameter (d) of the beam is a normally distributed random variable with a mean of 50 mm and a standard deviation of 0.125 mm. The bending moment (M) is also a normally distributed random variable with a mean of 1750 N-m and a standard deviation of 150 N-m. Determine the mean and standard deviation of the corresponding bending stress variable (o). Comment on the analysis.
