Step 7. Determine the rear axle weight (RAW). The RAW is the total weight reading of the scales under the rear tires. Follow the procedures for step 5 and label the reading as RAW on the masking tape. Remember, the RAW is the weight readings of both tire scales added together and recorded in pounds.

NOTE: The RAW for vehicles with tandem axles is the weight of the IAW and the RAW added together and labeled above the trunnion (fig. 4-11).

Step 8. Compute moment 1 (M1). The formula for M1 is distance 1 times the forward axle weight, or D1 x FAW = M1.

Step 9. Compute moment 2 (M2). The formula for M2 is distance 2 times the intermediate axle weight, or D2 x IAW = M2.

Step 10. Compute moment 3 (M3). The formula for M3 is distance 3 times the rear axle weight, or D3 x RAW = M3.

Step 11. Compute the gross vehicle weight (GVW). GVW is determined by adding the axle weights. The formula for GVW is FAW + IAW + RAW = GVW.

Step 12. Determine the total moment (TM). TM is determined by adding all the moments. The formula is M1 + M2 + M3 = TM.

Step 13. Compute the C/B of the vehicle. This is done by dividing the GVW into the total moment, which
