In a compression test of a standard 2 by 2 by 8-in. douglas-fir specimen, the test data were as follows: load, lb. 0 | 5,000 | 10,000 | 15,000 | 20,000 | 25,000 | 30,000dial reading in 0.000 | 0.0085 | 0.0155 | 0.0225 | 0.0295 | 0.0365 | 0.0485the extensometer had a gage length of 6 in. and a multiplying factor of 2.compute the modulus of elasticity and the stress at the proportional limit.
