Question: 1 the bracket shown in figure 1 is to be...

Question details

1. The bracket shown in FIGURE 1 is to be used to mount an outboard motor onto the transom of a boat 200 mn 8 holes MIO thread 00 mn 20mm rad Surface for fixing motor 200 mm Surface for fixing to boat transom Consider that we need to predict the fatigue life of the bracket shown in FIGURE 1. If we are given that the following relationship applies for the bracket: da dN 10 12,(AK), = 4 × where ΔΚ is in MPa m and that the stress varies cyclically between 30 and 150 MPa, determine the number of cycles for a defect to grow from 1.5 mm to 4 mm
