Using the book of Juvinall, R.C., and Marshek, K.M. (2011), Fundamentals of Machine Component Design, 5th ed., John Wiley and Sons. Chapter 10. Complete the following problems;

Part II. Sizing problem For the bolted connection shown below: A. Determine the bolt diameter required to resist the loads shown in the figure. Use coarse threads for your bolt selection. B. Determine the plate thickness "h" required for the connection. Consider both failure modes of the plates as discussed in class. You can buy the plate in 1/16" increments (1/16", 2/16" = 1/8", 3/16", etc.) and the minimum available thickness is 1/16". %3D SHOW ALL YOUR WORK TO GET FULL CREDIT Notes: Use a Safety Factor of 2.5 for all the sizing calculations. Assume that the bolt material is SAE Grade 1. Assume the same strength (SAE Grade 1) for the plates. Use the Maximum Distortion Energy (von Mises) Failure Criterion for all the sizing calculations.
