The above freely supported light uniform portal frame consists of a vertical member of length 3m rigidly connected to a horizontal member of length am The vertical member is subject to two point loads of magnitudes F1 34 N and F3 = 76 N, at the positions and in the directions indicated above. In addition there is a uniformly distributed load of intensity - 220 N/m along the horizontal member, as shown Find the shear force V(x) and the bending moment M(x) at the points 1 - 113 m and 22 - 37 m along the appropriate members as depicted in the figure Give your answers correct to two significant figures As the point a 1 - 1.13m the shear force and bending moment are V() - 國防N and M(+1) 22 Nm Al the point 22 -3.7m the shear force and bending momentare, V(2) - BEN and M(+2) Nm Each correct answer is worth up to one mark. These questions require your answers correct to two significant figures, if your answers are only correct to one significant figure then half the full marks will be awarded
