If the Ares SRBs will be higher in size and pressure it will affect the
joints. The higher pressure will cause more lengthening of the whole
SRB at ignition. If the putty fails to follow that a diaster seems
certain. Of similar impact is the larger bending such a higher
SRB will have. The final burn through in case of Challanger may be
caused by such bending while the shuttle crossed a shear wind layer.
This wind load was still inside the specs (I never heard otherwise)
and only the final tip to disaster. In case of Ares-1 it may be
something to be considered carefuly. But if the SRBs of Ares are
not for reuse the problem may be good to fix. Just glue it together.

Ares supposed to be reusable

Add the violent shaking and its a recipe for disaster.

sure hope they move to existing expendables for astronauts

then to keep the contractors happy and the pork money going go with
shuttle C for heavy lift

using the existing pads what would shuttle Cs top weight capacity to
orbit be?
