For A Bronze Alloy, The Stress At Which Plastic Deformation Begins Is 280 MPa, And The Modulus Of Elasticity Is 115 GPa. (A) What Is The Maximum Load That May Be Ap- Plied To A Specimen With A Cross-Sectional Area Of 325 Mm2 Without Plastic Deformation? (B) If The Original Specimen Length Is 120 Mm, What Is The Maximum Length To Which It May Be Stretched

 

 

 

8.7 For a bronze alloy, the stress at which plastic deformation begins is 280 MPa, and the modulus of elasticity is 115 GPa. (a) What is the maximum load that may be ap- plied to a specimen with a cross-sectional area of 325 mm without plastic deformation? (b) If the original specimen length is 120 mm, what is the maximum length to which it may be stretched without causing plastic deformation?
