Experts, can you please help me with this. I need a query to produce the IDTPartNumber and Description from the Equipment Table. And then I need the sum of Qty from the SalesEquipment table for the IDTPartNumber. And I need to find these based on year. So SalesDate Between #1/1/2014# and #7/25/2014#.

It looks as if there should be a many-to-many relationship here, with SalesEquipment as the junction table.  It would be best to set up this relationship, to ensure referential integrity.  Can you post the database (or a cut-down version of it)?  I would like to have the actual tables to work with, but it might be possible to just use the appropriate fields from all three tables in a query, or if that doesn't work, make a date-limited query based on the Sales table, and link that to the other two tables to get the fields you need.  Then either do a Sum on Qty in that table, or save that query as a select query, and make a totals query based on it to get the sum.

Use the QBE to build the query.  It is a big help when you are unfamiliar with SQL syntax or just don't want to type it all out.

Add the three tables to the QBE.
Draw the join lines as indicated.
Select the desired fields.
Press the big sigma button to make this a Totals query.
Change "group by" to Sum for the Qty field
Add Between #1/1/2014# and #7/25/2014# to the criteria cell for the SalesDate column
Change "group by"  to Where for the SalesDate column (if you don't do this, you'll get a sum for each day in the range rather than a sum for the whole range.

PS - my personal preference is to NEVER use "ID" as the name of the primary key.  I suggest always using a meaningful name.
