Hello,
I have a data model that consists of three tables, one fact table, and two dimensions. The dimensions are both joined to the Fact with a one-to-many relationship
I have been asked to find the max date from one dimension (Dim A) for each element in my second dimension (Dim B). I think I need to use Calculate here but I'm not sure how.

Goal results
Your indicated expected results cannot be achieved. Both dimensions (Category and Date) will be aggregated if combined with facts, so you cannot have two rows of B and only one row of A.
What you will need to do is create a measure that crawls through the data model
MaxDate =
var c = ADDCOLUMNS(VALUES(_FactValues[FactKeyA]),"FA",_FactValues[FactKeyA])
var d = ADDCOLUMNS(c,"MD",CALCULATE(max(_DimDate[Date]),Filter(_DimDate,_DimDate[FactKeyA]=[FA])))
return MAXX(d,[MD])
See attached for an implementation
Another alternative is to show the raw data, the dimensions without the facts.
See attached.
