Grade 2:1.200كلغ(0.325kg+2#0.875kg weight)= 11.77n

Grade 3:2.160kg=(0.325kg+3#1.835kg weight)= 21.18n

Grade 4:3.800kg=(0.325kg+4#3.475kg weight)=37.26N

Grade 5:5.000kg=(0.325kg+5#4.675kg weight)=49.03N

Grade 6:10.000kg=(0.325kg+5#4.675k weight +6#5.000kg weight)=98.07N

Grade 7:12.500kg=(0.325kg+5#4.675kg weight +6#5.000kg weight +7#2.500kg weight)=122.58N

Grade 8:21.600 kg=(0.325kg+2#0.875kg weight +3#1.835kg weight +4#3.475kg weight +5#4.675kg weight +6#5.000kg weight +7#2.500kg weight +8#2.915kg weight)= 211.82n
