(19) Figure Q19 shows a framework consisting of horizontal members 3 m long and vertical members 4 m long. The framework is loaded at joints J and L with downward load forces of 2 kN. The applied forces cause a vertical reaction forces at A and G and no horizontal reaction force. You are asked to find the internal force in member JK - what would be your approach to solve this problem? Explain your solution process and some of your results by filling in the blanks below. 2 kN 2 kN H RAY RAX A K M N B C D E F 3 m 1 RGY 4m Fill in the multiple blanks. Figure Q19 Finding the vertical reactions is the starting point which can be done by taking moments at A and G but since this is symmetrical loading case the vertical reactions can simply be calculated by halving the total loading 4 kN. Ideally, we can solve the problem using the Method of cutting through the members JK, DJ and It would be sensible to select the left-hand side of the diagram as there are less full members and only one force…

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me answer all the questions below? Especially the one about the bending moment and shear force. The Figure 2 attached is a simplified structure to undertake a structural analysis on a concept design for a low cost stroller/buggy for children. The buggy consists of a number of metal sections that are pin-jointed together. The buggy is designed to accommodate a child of mass no more than 20 kg, sat on the seat which is supported at four points (Fc) on the frame of the buggy. Assume that the weight of the child is equally distributed across all of the points indicated on Figure 2 as Fc. Assume that there are no additional forces applied to the handle of the buggy, that the buggy is static (stationary) and that the buggy, and the elements of the frame have no mass. At points A and G, there are roll supports. At Points B, F and D there are the pin supports. I am required…

Identify 3 car’s components in general, one subjected to tension, the 2nd to compression, and the 3rd component subjected to a shear force. Find a suitable factor of safety of your components and calculate the working stresses and strains for each of your components. Assume values to do the caculations. How does an increase in operational temperature affect your results?
c. Determine critical load and critical stress for the column/axial member. Justify selection of the formulas for the calculationsInformation provided: i) Boundary/end conditions: In this instance, the column is assumed to be fixed at both ends, simulating conditions where the column is integrally connected to the floor slabs above and below, a common condition in many mechanical design contexts. ii) External axial load: Assuming the column supports a floor with a uniformly distributed load, we've calculated the total axial load on the column to be 453.589 kN. iii) Properties of the column: The cylindrical column is composed of steel, a commonly used material with a known Young's modulus (E) of approximately 200 GPa. The steel has a yield stress of around 250 MPa and ultimate stress near 400 MPa. The diameter (d) of the column is 0.3048 m, providing a cross-sectional area (A) of π*(d/2)² = 0.073 m².
