Answer to Question #230786 in Civil and Environmental Engineering for Vasu

Question

Draw BMD and SFD for an overhang beam ABC with span BC overhanging. The
loading and span data is as follows
Span AB = 6 m; Full Span UDL = 20 kN/m,
Span BC = 2 m; Full Span UDL = 30 kN/m
Span BC = 6 m; Point Load at C = 15 kN.

Answer 1

=-(15x8)+(-30x2)(7))+R_Bx6-(20x6)x3)

 =-120-420+6R_B-360

 0=6R_B-900 

900=6R_B  

R_B=150  

R_A=45  

Bending moments 

BM_c=0 

BM_b=-30-60=-90

BM_A= -15x8-(6x70)+(150x6)-(120x3) 

=0
