(uscs units) a tensile test specimen has a gage length = 2.0 in and diameter = 0.798 in. yielding occurs at a load of 31,000 lb. the corresponding gage length = 2.0083 in, which is the 0.2 percent yield point. the maximum load of 58,000 lb is reached at a gage length = 2.47 in. determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) if fracture occurs at a gage length of 2.62 in, determine the percent elongation. (e) if the specimen necked to an area = 0.36 in2 , determine the percent reduction in area.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
