For a brass alloy, the following engineering stresses produce the corresponding plastic engineering strains prior to necking: engineering stress (mpa) engineering strain 315 0.105 340 0.220 on the basis of this information, compute the engineering stress necessary to produce an engineering strain of 0.28.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
