7.34 Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Label all significant points on each diagram and identify the maximum moments along with their respective locations. Additionally: (a) Determine V and M in the beam at a point located 0.75 m to the right of B.

A structure is subjected to force as shown in the figure below. Assuming that the EI of the entire structure section is constant, try to analyze this structure and draw the shear curve (Shear Curve) and bending moment diagram (Moment Curve) of the beam ABCD.

2.0 m ㅏ F 3.0 m q 4.0 m The above freely supported light uniform beam of length 10 m carries a point load F = 45 kN and a uniformly distributed load q = 23 kN m −1 at the positions indicated. Find the shear force V (x) and the bending moment M(x) at the following points along the beam. Give your answers correct to two significant figures. At the point x = 4 m the shear force and bending moment are: V(4) and M(4) = KN kN m. At the point x = : 8 m the shear force and bending moment are: KN = V(8) and M(8) = kN m 1.0 m + -+
