Answer to Problem 2.1EAA
Engineer’s job role- Thermal and Structural Analyst.
Explanation of Solution
I met a
When a turbocharger has to be produced, it has to undergo various stages such as design, drafting, analysis, testing and manufacturing. Analysis is a critical phase where the results are used to determine the impact of Thermal and Structural loads on Turbo chargers. In other words, the results help in evaluating whether the product will be able to withstand stresses and loads expected of it.
Structural Analysis incorporates the field of Strength of Materials, Applied Mathematics and Material Science to compute a structure’s deformations, internal forces, stresses, and support reactions. Modern computational techniques such as Finite Element Methods have been used for complex 3D models, wherein a component is divided into finite elements to get the results. So, the job requires him to use Finite Element Methods (FEM) along with traditional hand calculations to carry out the Thermal and Structural analysis of turbochargers and to get the results. He has to apply his
His contributions as a structural analyst will also help reduce the number of tests to be performed on the product. This in turn will save time, money and man power which otherwise is required for testing.
This role can be compared with ‘Analysis’ job function in the text book where an analysis engineer uses mathematical models and computational tools (FEM in the above case) to provide the necessary information (like cause of failure and input on redesign in the above example) to the design, development and research engineers to help them perform their function.

- How do i solve this problem?arrow_forwardQ4/ A compressor is driven motor by mean of a flat belt of thickness 10 mm and a width of 250 mm. The motor pulley is 300 mm diameter and run at 900 rpm and the compressor pulley is 1500 mm diameter. The shaft center distance is 1.5 m. The angle of contact of the smaller pulley is 220° and on the larger pulley is 270°. The coefficient of friction between the belt and the small pulley is 0.3, and between the belt and the large pulley is 0.25. The maximum allowable belt stress is 2 MPa and the belt density is 970 kg/m³. (a) What is the power capacity of the drive and (b) If the small pulley replaced by V-grooved pulley of diameter 300 mm, grooved angle of 34° and the coefficient of friction between belt and grooved pulley is 0.35. What will be the power capacity in this case, assuming that the diameter of the large pulley remain the same of 1500 mm.arrow_forwardYou are tasked with designing a power drive system to transmit power between a motor and a conveyor belt in a manufacturing facility as illustrated in figure. The design must ensure efficient power transmission, reliability, and safety. Given the following specifications and constraints, design drive system for this application: Specifications: Motor Power: The electric motor provides 10 kW of power at 1,500 RPM. Output Speed: The output shaft should rotate at 150 rpm. Design Decisions: Transmission ratio: Determine the necessary drive ratio for the system. Shaft Diameter: Design the shafts for both the motor and the conveyor end. Material Selection: Choose appropriate materials for the gears, shafts. Bearings: Select suitable rolling element bearings. Constraints: Space Limitation: The available space for the gear drive system is limited to a 1-meter-long section.
