For the beam and loading shown, (a) draw the shear and bending-moment diagrams, (b) determine the maximum absolute values of the shear and bending moment.

TEXT:A planar construction is composed of two beam elements and two axial rods. These arejoined with frictionless joints, as indicated on the sketch. The structure is applied an outer concentrated load P=8kN in node G and a downwardevenly distributed load q=4kN/m between junctions A and D. The beam ABCD and EFG are torque rigid,while the axial rods BF and CF only absorb forces in the direction of the rods. A) Calculate the rod forces and for the external given load effect.B) Calculate the bearing reactions for the external given load effect.

The outer diameter of the solid steel pipe shown in the figure is 25 mm. If the pipe is fixed at point E as in the figure andIt is subjected to a force of 800 N, a torque of 45 N.m and a moment of 300 N.m, applied from the other end of the pipe as in the figure.if left, it will occur at point A;(a) Principal planes (@p1, Opz),(b) Principal stresses (Omax, Omin),(c) the view of the principal plane, Note: Point A is on the top and outer surface of the steel pipe. The line AB is parallel to the z-axis andpassing through the center
