Replace the distributed loading by an equivalent resultant force and specify where its line of action intersects a horizontal line along member AB, measured from A. A 4m 2 kN/m

3. The cross section of a weightless quarter circular gate AB of width 0.9 m is shown in Figure 3.The hinge is along AA. Calculate the force R at B to hold the gate in this position.

In the system shown in the figure, parts AB, BC and CD are of equal length and 4 m. Clockwise from point AA moment of 10 kNm is applied in the opposite direction. The distributed load of 3 kN/m at BC is upward. Beam DA load of 5 kN was applied downwards from the point. The profile of the beam has a 100 mm edge as seen on the right side.was formed by subtracting a circle with a diameter of 80 mm from the center of a regular hexagon of length. Accordingly; A)Calculate the reaction forces at B and C B)Draw shear force and bending moment diagrams C)Calculate the maximum bending and show it on the bending moment diagram. D)Calculate the sectional moment of inertia of the profile E)Calculate the maximum stress in the beam NOTE:For option C, you need to obtain a parobolic expression when drawing the bending moment diagram. You need to use derivation.
