Complete Table P4.2. For a member where a deflection criterion controls,which material would require a larger cross section? What about for a member where tension controls?
6. Give the properties table below. A992 Steel 7178 T76 Aluminum Yield Strength 50 ksi 73 ksi Ultimate strength 75 ksi 85 ksi Modulus of Elasticity 29,000 ksi 10,500 ksi Assume you are designing a rectangular member with a specific allowed height. For a design where deflection criterion controls which material would require a larger cross section? For a design where tension stress controls, which material requires the larger cross section?
} 8) A tensile load of 3000 N is applied to a steel bar of cross-sectional area 500 mm?. If a tensile load was applied to an aluminum bar to achieve the same lateral (transvers) strain with the former (steel bar), what would be the load? Note: Original dimensions of the two bars are the same (Est = 2.1 x 105 MPa, Eat = 0.703 × 105 MPa, vg = 0.3, vat = 0.33) E = º , v = - Saterat Eaxial Fatuminum™ 3000 N A-500 mm² A=500 mm² Fatuminum=? 3000 N Steel Aluminum
