Apolymeric cylinder initially exerts a stress with a magnitude (absolute value) of 1.627 mpa when compressed. if the tensile modulus and viscosity of this polymer are 16.1 mpa and 2 ×1012 pa-s, respectively, what will be the approximate magnitude of the stress, in mpa, exerted by the spring after 1.3 day(s)?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
