NAME:_________________________________ LAB SECTION NUMBER:_____________________ ME350 Fall 2011 Homework #4 (35 points total) Due Thursday October 6, 2011 by 1:30pm Hand in at the beginning of Lecture 1. (25 pts) A bolted joint is subjected to a fluctuating tensile load whose maximum value is 8 kips (kilopounds). The bolt is a 5/8-11 UNC thread, SAE Grade 8. Use a value of 7.3 Mlbf/in for k b (stiffness of the bolt), and 19.4 Mlbf/in for k m (stiffness of the members). Assume that the bolt may be
