Answer
# 1
singly reinforced beam is reinforced at tension zone alone
and doubly reinforced beam is reinforced at both zones and
difference is singiy cannot take too much loads

Answer
# 2
when rf is reqd in only tensile zone of beam, its called
singly rc beam, when moment is large enough is to reqd to
provide rf at compression zone also,called douly rc beam.
load variation is the only difference betn these two.

Answer
# 3
In singly reinforced beam limiting moment of resistance is higher than design moment. And the reinforcement designed for tension zone only.
In doubly reinforced beam limiting moment of resistance is lower than design moment. And the reinforcement designed for both tension zone and compression zone.
