- At equilibrium E Fy=0 Rat Rc-(12 x 2)-40=0 - RATR c = 64 --(1) » At equilibrium, moment at A=0 EMA=0 :- (1282) (+) – Rc (2)

s hear Force Sof, at A, E = -8 SF before C, Fc = RA- (12 x 2) --8-24=-32 KN SF at C, Fc=Fctre - = -32+72= 40 kn SF at B, Fo=

Maximum shear load = 40 kN

Maximum bending moment = 40 kN/m

Q-2

at equilibrium, - Efy=0 Rot RB- (3082) - 60=0 2 RATRB = 120 ----(2) moment at A=0 , EMA=0 ra (Box23 (1) + (60x3) - RB X 5 =0

Shear force -sf @ A, FA = 72 KN - sf at C, Fc=RA- (3082) 72-60=12 kN - SF @ D, Fo= F(-60=12-60 = -48 kN -SF@B, Fo= For RB= -

Bending moment - MASO -m, = RAX2 - (3082) (1) = (72X2) – 60 =84 INm -Mo- Rox3-(30x2) (2) (7243)-(120) = 96 kNm -Mo=0

N7109 - 30kN/m A zm RA 32 Diq -48 В М. 8496

Maximum shear load = 72 kN

Maximum bending moment = 96 kN/m
