Question

The client wants to immediately investigate the cause of this failure and demonstrate that the design of the cantilever truss structure was flawed so they can recoup their costs through legal means. Furthermore, there will be the opportunity to bid for the design of a new and improved cantilever truss structure if you can demonstrate the original cause of failure. Figure 1 Cantiever truss design shown before the deflection has occurred The cantilever structure consists of two parallel trusses and is held by supports as shown in Figure 1. The total truss length is 15 meters long, 3.5 meters wide and has a height of 1 meter The conveyor belt system, including elements such as the idlers and belt but excluding the truss has a mass of around 90 kg/m2 on average over the length and width of the truss (looking down from above). A funnelling system has a mass of around 800 kg and is welded to the free end top joint. The bulk density of the aggregate rock is graded on average at 1650 kg/m3 and is sent down the belt with a nominal width of 0.8 m and a nominal height of 20 cm. Table 1 Truss member properties of stainless steel Material Property Yield Strength Ultimate Tensile Strength Density Mean (average) Rodius Thickness Value 215 MPa 505 MPa 7700 kg/m 0.07 m 0.0035 m There is an opportunity for you to acquire another fee from this project by presenting the client with a truss design that will not fail as the previous structure did. The TrussGen2 must be of the same dimensions (length, width, height) and must be designed to fit to the already constructed supports. You must provide a design and material specification for the new truss structure. The Client would like to expand their operations in the future and, therefore, TrussGen2 must be able to hold 3 times the original aggregate rock load.

Answer 1

Given diagram as: conticeves truss design given table of data doublerightarrow the above diagram have llel kusses & held by support doublerightarrow mass = 90 kg/m^2 total kuss length = 15 long = 3. 5 wide = 1 height. funelling system mass = 500 kg bulk density = 1650 kg/m^2 belt nominal width = 0. 8 m height = 20 cm doublerightarrow according to given data: from the methodology: - rightarrow conduct a literature review of failure investigation process rightarrow develop a failure investigation quentiance rightarrow collecting data through gravey of engineering rightarrow conduct a analysis of surey result and case students rightarrow develop a modified failure investigation process here results & rightarrow the most of are all request case of failure rightarrow what can we done to improve the process of investigation
