Brake pads are a component of disc brakes used in automotive and other applications. Follow the steps to complete a brake pad analysis.  Answer questions in the quiz related to this problem. Download instructions, the geometry file and the archived file here. #### (2) Paperclip analysis

A paper clip is a functional little tool that everyone is familiar with. Follow the steps to complete the analysis and review the results. Try to answer the questions below when reviewing the model.

a. Given the condition that when equivalent strain reaches 1.2E-3, the deformation of the paper clip will not be recoverable, i.e., the material will be plastically deformed, decide if the paper clip in this analysis can recover its original configuration.

b. The result of the simulation is the true strain. Calculate the engineering strain for the maximum equivalent strain value.
