**Bracket Seat Assembly Bending Stress Analysis**A part of a bracket seat assembly of a bus is shown in the figure below. The load on the bracket varies from 2,500 N to 500 N as passengers enter and exit the bus. Considering the beam at the place where the maximum bending stress would occur, calculate:(a) Maximum stress (b) Minimum stress (c) Mean stress (d) Alternating stress (e) Stress ratio, R.(f) Draw a stress vs. time graph and show the variation of the stress by marking minimum, maximum, alternate, and mean stresses on the graph. You can use MDSolids to draw a moment diagram and to identify the location of the highest bending moment.**Diagram Explanation:**- The diagram shows a bracket supported at each end by simple supports.- The load is applied vertically downward on the bracket at a distance of 175 mm from the left support and 275 mm from the right support.- The total distance between the supports is 450 mm.- A cross-section labeled A-A is indicated, with dimensions: 60 mm width and 12 mm thickness.This setup allows for analyzing the bending stress on the bracket as the load varies, which simulates the effect of passengers moving in and out of the bus. The goal is to ensure the bracket can handle the varying stresses safely.
