Is it possible to produce a continuous and oriented aramid fiber–epoxy matrix composite having longitudinal and transverse moduli of elasticity of 35 gpa (5 × 106 psi) and 5.17 gpa (7.5 × 105 psi), respectively? why or why not? assume that the elastic modulus of the epoxy is 3.4 gpa (4.93 × 105 psi).

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
