# 031-06 CARGO HANDLING

### Course Information

In the previous chapter, we have determined the CG position using loading graphs given in sample documents. In this chapter, we are going to determine the CG position by using the formula: CG position equals total moment over total mass. Consider a weight less beam, and we place a mass of 5 kilograms, 2 meters aft of datum and a mass of 10 kilograms 5 meters aft of datum. If we calculate the total moment, the total moment equals 5 kilograms times 2 meters plus 10 kilograms times 5 meters which is equal to 60 kilogram meters. Now let”s draw the same beam, and we know that the total mass which is 10 kilograms plus 5 kilograms or 15 kilograms is acting through the centre of gravity. We can say that the total mass is creating the same total moment because the whole system is the same. Total moment equals total mass times the CG distance from the datum. If we arrange the formula you see that CG distance from the datum is equal to total moment over total mass. Total moment of 60 kilogram meters over total mass of 15 kilograms is equal to 4 meters. Courses are constantly monitored and updated when major changes in authority documentation is released.
