It has been shown that certain shapes of metal beams are stronger than other shapes. for example, i-beams are stronger than rectangular solids of the same size. designers must often take into account the strength requirements for an application and weigh these requirements against cost and availability.
what kind of test would a designer perform to get the strongest material for his application?
a) bending different materials of the same shape
b) bending different materials of different shapes
c) bending different cost materials of the same size
d) bending different cost materials of the same shape
