    (a) Design calculations must include both side and bottom damage, 
applied separately; and
    (b) Damage must consist of the penetrations having the dimensions 
given in Table 172.235 except that, if the most disabling penetrations 
would be less than the penetrations described in this paragraph, the 
smaller penetration must be assumed.
