During the plastic deformation portion of a uniaxial compression test, two cylindrical specimens first maintain its cylindrical shape (decreasing in length and increasing in diameter), then:
a. Specimen 1 transitions into barreling (the specimen attains a barrel shape) and the breaks.
b. Specimen 2 breaks without barreling.
Give, in two separate paragraphs with no less than eight (8) lines each, your explanation for these
two behaviors.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
