1.Support reaction calculation:
∑MA=0 (↻+ve)15×2+10×2−VD×7=0Vd=7.14 kN↑∑FY=0(↑+ve)VA−10+7.14=0VA=2.86 kN↑∑FX=0(→+ve)15+HA=0HA=−15 kN←
2.Consider part 'AB'
BME=15×2=30 kNm_ [For BMD always see the original diagram]
3.Consider part 'BC'
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'
