In a compression test, a steel test specimen (modulus of elasticity = 30 x 106lb/in2) has a starting height= 2.0 in and diameter = 1.5 in. the metal yields (0.2% offset) at a load = 140,000 lb. at a load of 260,000 lb, the height has been reduced to 1.6 in. determine (a)yield strength and (b) flow curve parameters (strength coefficient and strain-hardening exponent). assume that the cross-sectional area increases uniformly during the test.

Who was the first scientist to measure speed as distance over time?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
