(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.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
