Problem No. 3 (20 Points) The mass, length and diameter of a cylindrical object is established through the following measurements to calculate its density. m=5.5 lbm with u - 0.1 lbm, and instrument uncertainty of 0.5% of reading. m L-6.5 in. with 0.01 in. and instrument uncertainty of 2% of reading. D = 3.75 in. with MOD = 0.001 in, and instrument uncertainty of .1% of reading. a) Find the density and estimate its design stage uncertainty. b) Which measurement method contributes most to the uncertainty in the density calculation? u vor
