Figure 4-11.—Marking procedures.Step 7. Determine the rear axle weight (RAW). TheRAW is the total weight reading of the scales under therear tires. Follow the procedures for step 5 and label thereading as RAW on the masking tape. Remember, theRAW is the weight readings of both tire scales addedtogether and recorded in pounds.NOTE: The RAW for vehicles with tandem axles isthe weight of the IAW and the RAW added together andlabeled above the trunnion (fig. 4-11).Step 8. Compute moment 1 (M1). The formula forM1 is distance 1 times the forward axle weight, orD1 x FAW = M1.Step 9. Compute moment 2 (M2). The formula forM2 is distance 2 times the intermediate axle weight, orD2 x IAW = M2.Step 10. Compute moment 3 (M3). The formula forM3 is distance 3 times the rear axle weight, orD3 x RAW = M3.Step 11. Compute the gross vehicle weight (GVW).GVW is determined by adding the axle weights. Theformula for GVW is FAW + IAW + RAW = GVW.Step 12. Determine the total moment (TM). TM isdetermined by adding all the moments. The formula isM1 + M2 + M3 = TM.Step 13. Compute the C/B of the vehicle. This isdone by dividing the GVW into the total moment, whichFigure 4-12.—Center of balance of tracked vehicle.4-26
