# Vector question on component subscripts

What does A1mean? This A1 component does not even have a X subscript.

Then there's A1x and resultant R2.

Can anyone give an example on how to interpret and graph both vector components & resultant from a problem?

Do you have a specific question, or context, in which you've seen this?

It's lab, but I haven't seen this in the book.

1 Mount a pulley at the 20 degree mark on the force table and suspend a mass of 100 grams over it. This gives a force A1. Next, mount a second pulley at the 120 mark and suspend amass of 200 grows over it, giving a force A2.

a. Calculate the magnitudes of these forces, their representive langhts, and their components. Record these calculations in table 1.

b.Draw a vector diagram for A1 & A2 with their lengths represented in centimeters. Use the parallelogram method to add these vectors geometrically to get the resultant vector R1=A2 + A2.
