Chapter 13, Problem 123CP

Hi, can you please assist with the attached question please. Please do not use Ai software. Many thanks.

determine the allowable bending and contact stresses for a grade 1 steel through-hardened to 250 HB. Assume the desired reliability is 50% and that the pinion and gear have the same hardness and the gear encounters hydrodynamic lubrication and is to last ten million cycles

Using the four-point bending tool, detail the influence of both applied load and notch size on the transverse strain. Cover the following points in your answer. a. A detailed description of the methodology you have used to create a set of results suitable to answer this question. Include details on the placement of line scans, the loads used, etc. (there is no need to describe the process of extracting the data from the interactive or the fundamental principles behind DIC). (5 marks) b. A description of the results you have found, including a written description, images, and both vertical and horizontal line scans from the four-point bending tool. Include a minimum of three loads and three notch sizes in your results. (20 marks) c. The conclusions you can make regarding the influence of load and notch size on the strain experienced by the beam based on the data you collect. (5 marks) To achieve full marks, you will need to include the following in your work: • properly labelled graphs…
