Unformatted text preview: 530.215 MECHANICS-BASED DESIGN Homework VIII Due April 20, 2009 Design Project 2 1 The man in the image likes to climb up the vertical crevice near his house. The cliff walls are a total of 300 feet high, and as he’s getting older, the climb is harder for him to make. The problem here is to create a device that the man can use to take a break from climbing and rest on. He will have to be able to transport this device up and down the cliff wall every time he wants to climb. Additional Problem data: - The cliff walls are vertical, with a distance of 4 feet, ± 2 inches apart (the width varies slightly at different points). - Although completely unphysical, to simplify this problem and focus on stress analysis we can assume a friction coefficient equal to 1, if necessary for your design. - You are not creating a permament post: he’ll carry the device with him, and use it whenever he feels too tired....
