Problem 3.20

Determine the moment about the origin O of the force F = 2i + 3j 4k that acts at a Point A. Assume that the position vector of A is (a) r = 3i 6j + 5k, (b) r = i 4j 2k, (c) r = 4i + 6j 8k.

PY 205 with Daniel Dougherty Week 1 Chapter 1 1/12/2016  Theory – broader, more detailed and can give quantitatively testable predictions, often with great precision  Law – certain, concise but general statements about how nature behaves  Principle- less general statements o Scientific laws are descriptive because they describe how mature behaves  Uncertainty and percent uncertainty o Ratio of uncertainty to the measured value X 100 to make it a percent o Ex: 8.8 +/- .1cm .1/8.8 X 100 = 1%  Significant figures o 0 is a placeholder o Ex: 80  one significant figure since 0 does not count o RULE: number of significant figures in the last number should be the s
