1.Support reaction calculation:

MA=0 (+ve)15×2+10×2VD×7=0Vd=7.14 kNFY=0(+ve)VA10+7.14=0VA=2.86 kNFX=0(+ve)15+HA=0HA=15 kN


2.Consider part 'AB'

enter image description here

BME=15×2=30 kNm_ [For BMD always see the original diagram]


3.Consider part 'BC'

enter image description here

BM calculation :

B.MB=30 kNmB.MF=7.14×5=35.7 kN.m_B.MC=7.14×3=21.42 kN.m_


4.Consider part 'CD'
