A cylindrical bar of metal having a diameter of 18.9 mm and a length of 207 mm is deformed elastically in tension with a force of 52300 N. Given that the elastic modulus and Poisson's ratio of the metal are 65.6 GPa and 0.35, respectively, determine the following: (a) The amount by which this specimen will elongate in the direction of the applied stress.
(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number. (a) 0.588 mm

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.
