h2. Problem Specification


h4. Geometry

A preeminent bicycle company is disappointed with the negative feedback they have received on their latest model, and they have pinpointed the problem to an outdated bicycle crank design that they assumed would still withstand typical loads. To protect their reputation, they have outsourced the task of redesigning the crank to you, providing you only with the geometry shown below. The material they selected has an Youngs is aluminum (AA6061T6), and .The three-dimensional bicycle crank shown below is being evaluated for use on a bicycle.
