Is the contact point D an axis of fixed rotation? A. yes B. no D About center of mass c. ! r M o = I o r " # ! r M c = I c r " # About fixed axis O. About any point P ! r M p = Ic r " # + r r c / p $m r a c Net torque - rotation Stated instrument precision of 1E-8 m/s/s. Standard deviation ~ 5E-8 m/s/s (in the right ballpark) Some tables stated: g = 9.8126 Standard deviation is 5.9745364867E-8 Unit errors in Earth tide correction For the 17th century question, some people didn’t give the answer in seconds. Or used imprecise latitude for Paris. If you find (and remove) an outlier, you need to compute a new mean and a new standard deviation, and look for outliers again (until you don’t find anymore). %Time Pos(deg) y (mm) omega (deg / s) v (mm / s) 0.000000 21175.056641 202.100922 1129.943481 131.392059 0.010000 21185.935547 202.100922 1089.918213 0.000000 0.020000 21196.576172 197.710800 1113.430786 -439.011383 0.030000 21207.535156 193.457687 1106.500732 -425.311737 0.040000 21220.335937 183.033493 1095.890381 -1042.418579 Collar position: The system can resolve +/-0.1mm, the sensor is only specified as accurate to +/- 2.3mm.
