Reaction Calculation:
∑MA=0RB×5.5=(2×2)×1+1.5×2+30RB=6.72kNΣFy=0RAA+RB=(2×2)+1.5RA=−1.22kN
2) SF Calculation:
SF at A=−1.22kNCL=−1.22−(2×2)=−5.22kNCR=−5.22−1.5=−6.72kNBL=−6.72kNB=−6.72+6.72=0kN(∴ ok )
3) BM Calculation:
BM at A and B=0(∵ Supports A and B are simple )C=−1.22×2−(2×2)×1=−6.44kN−mDL=6.72×2.5−30=−13.2kN−mDR=6.72×2.5=+16.8kN−m
