1. As an engineer, you work for a company that makes mountain bicycles. Some bicycles that have been in use for several years have had handlebars that failed by completely breaking off where the handlebar is clamped into the stem that connects it to the rest of the bicycle. What is the most likely cause of these failures? Describe some of the steps that you might take to redesign this part and to verify that your new design will solve this problem.
2. Repeat Prob. 1. for failures in the cast aluminum bracket used to attach the rudder of a small recreational sailboat.
