A rod consists of a binder and two types of filamentous reinforcement with the following constituent properties.

Material        Density (g/cm3)       Wt. %     E (GPa)          

Binder                   1.3                    35    3.5                .06

Fiber A                  2.5                    45           70                 1.4

Fiber B                  1.6                    20           6                   .45

a)      What maximum load can this rod carry without rupturing any of the constituents? Assume the cross-sectional area of the rod-10cm2.

b)      What is the maximum load the rod can carry?

c)       What constituent will rupture last?
