1- In a composite material a-the orientation of the fibers does not affect the overall strength of the composite. b-the fibers and matrix material dissolve together to form a solid solution. c-Much of the overall strength comes from the fibers rather than the matrix d-it is important that the matrix material remains stiff and does not deform 2- Steel with a fine grain structure rather than a course grain structure will generally be a-Higher modulus b-Lower strength and more ductile c-higher strength and more ductile d-Higher modulus but more brittle 3- Which of the following represent a molybdenum steel with . 30% carbon content? a-304 b- 1304 c-3004 d4130 4- Which of the following types of steel is used for punches and presses, crankshafts, axles, etc. requiring moderate to high strength? a-Low carbon steel b-High carbon steel| c-Medium carbon steel d-Stainless steel
