Acontinuous and aligned fibrous reinforced composite having a cross-sectional area of 970 mm2 is subjected to an external tensile load. if the stresses sustained by the fiber and matrix phases are 215 mpa and 5.38 mpa, respectively, the force sustained by the fiber phase is 76,800 n, and the total longitudinal composite strain is 1.56 × 10-3 , determine the following: (a) the force sustained by the matrix phase (b) the modulus of elasticity of the composite material in the longitudinal direction (c) the moduli of elasticity for fiber and matrix phases

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

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.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
