Welcome to A.S!
Ripping chains are ground at different angles to optimize that type of cutting: that means that they are not optimized for other types of cutting. They will still cut somewhat.
'Crosscutting' = cutting across the grain. This includes 'falling', 'limbing', and 'bucking'.
'Ripping' is cutting into the end of a log, such as when 'milling' it into boards.
'Noodling' is cutting a log or round in half with the bar and chain parallel with the length of the log. This produces long 'noodles' instead of small 'chips'.
