The mechanical properties of aluminum may be improved by incorporating fine particles of aluminum oxide (al2o3). given that the moduli of elasticity of these materials are, respectively, 69 gpa (10 × 106 psi) and 393 gpa (57 × 106 psi), plot modulus of elasticity versus the volume percent of al2o3 in al from 0 to 100 vol%, using both upper- and lower-bound expressions.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
