No, the tank is strong enough.  It has to be.  From assembly to launch,
the orbiter hangs on the side of the tank and the tank hangs between the
two SRBs.  Only the bases of the SRBs are supported.  (In fact, the bases
of the SRBs are bolted to the mobile pad, using pad-mounted bolts and great
big explosive nuts.  The nuts are blown at the same instant that the SRB
igniters fire.)
