Determine As,min for the following beam given that f’c = 7,250 psi and fy = 60,000 psi.

(05.02 MC)Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. Likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. What can be inferred from these observations?

(05.02 HC)A farmer found that caterpillars were eating his corn. He sprayed his field with pesticide to kill them. For the first three years, this treatment worked well, leaving only a few caterpillars in the field. Based on what is known about natural selection, what can he expect in succeeding years if he continues to use the same pesticide?
