% MEAM 147 Lab 6 % Stress, Strain, and Hooke's Law: % Stretching Rods of Varying Material and Geometry % Professor K. J. Kuchenbecker % October 14, 2007 % Description % ----------- % This script performs error analysis on measurements of the mass hung on a % solid rod and the corresponding deflections to enable calculation of % stiffness from a single measurement. Students should insert % their own data in the vector d and the variable Delta_d so they can see % how experimental error propagates through the calculations. Students % add their own expressions for the vectors k and Delta_k, based on error % analysis. The script provdes a place for students to insert their % expression for Young's modulus, E, and it computes the associated error, % Delta_E. The two main outputs from the script are a plot of the % experimental load and deflection data, with a linear fit, and text tables % of data printed at the command line. % Beginning % --------- % Clear previous variable values. clear; % Initial Parameter Definitions % ----------------------------- g = 9.8015; % m/s^2, acceleration due to gravity in Philadelphia. Delta_g = 0.002; % m/s^2, error of estimate in gravitational acceleration.
