One of Tony Stark's employees left a steel bar

next to a vibranium bar, and now he can't tell

them apart! He does know that the steel used

in this product has allowable stresses $98$ MPa

in tension or $42$ MPa in shear, and vibranium

can easily withstand those stresses. To find out

which is which, what tensile load $P$ must the

bar hold to prove it's vibranium?
