For a brass alloy, the stress at which plastic deformation begins is 345 mpa (50,000 psi), and the modulus of elasticity is 103 gpa (15.0 ×106 psi). (a) what is the maximum load that may be applied to a specimen with a cross-sectional area of 130 mm2 (0.2 in2 ) without plastic deformation? (b) if the original specimen length is 76 mm (3.0 what is the maximum length to which it can be stretched without causing plastic deformation?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
