Why did the members of congress and state delegates meet. in PA in may 1787

The members just met to deal with the problems of the United States of America, after the independence of the United Kingdom of Great Britain. Still, it may be that the intent of the Confederation, an intention of many proponents of the Convention, notably James Madison and Alexander Hamilton, was to create a new government rather than "fix" what already existed. The delegates elected George Washington to chair the convention. The result of the Convention was for the Constitution of the United States of America. The convention is one of the major events in the history of the United States of America.
