Question

..4953315 Determine the shear force (V) in kN at the point x = 1.75 m from point A for the beam as loaded in Figure 3.2a8. Given a = 1, b = 1, c= 1, P1 = P2 = 20. P, kN P, kN B C a m bm cm

Answer 1

P, = 20KN = 20KN TKB * Pi = P2 = 20 P2 20 B f RA k + a=im b=im Com x c=imt since 'A' is a hinge EMA =0 >> RB X 3 = 20 X1 + 20 x 2 SO Do RB = 20 KN RA = 20Kn shear force at to C A x from v = 20 KN C to D. shear force in portion v = (20-20) KN =0 KN Shear force in portion D to B. v = (20 -20-20) KN -20kn CS Scanned with CamScanner
