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? Period of Dr. Brown's pendulum Period of swing (s) 1.98 1.978 1.976 1.974 1.972 1.97 1.968 1.966 1.964 0 10 20 Number of swings since release 30 O Some random effect lowers the period of the pendulum by about 0.01 s in between the first and last data point. 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).
Mr. C studies the strength of the material used for a baseball bat, he knows that the strength is approximately normally distributed with a standard deviation of 175 psi. A random sample 30 specimens has a mean strength of 2,750 psi. a) What is the z-value when the mean strength is tested to be 3,000 psi, b) What will be the decision for the hypothesis testing with a=0.05 c) What is the minimum mean tensile strength needed from 30 samples, for the claim of 3,000 psi to be failed to rejected.
