# Foundations in Stress Analysis using Ansys Mechanical - Simulation Quiz 1

### Clothes Hanger Analysis

A clothes hanger is a hanging object in the shape of a human shoulder. It helps avoid wrinkles in clothes, and clothes can be easily hanged or removed from the hanger. When clothes or even a heavy cloth is hung on a clothes hanger, we usually see the hanger deform. In this problem, we will see how the clothes hanger made of different materials will deform under a light and heavy load.

1 / 10

Of the six strain tensor components, which has the largest magnitude for System A (Aluminum)?

2 / 10

Choose the BEST explanation for the influence of material density in the static analysis of the hanger.

3 / 10

Consider the triangular portion of the clothes hanger, with positive x-direction being the “right” side and negative x-direction being the “left” side.  For System B (Structural Steel), the Total Deformation is _____.  Select the BEST answer.

4 / 10

Choose the BEST reason for analyzing the hanger as a flexible body instead of a rigid body.

5 / 10

Choose the BEST reason for analyzing the hanger with a Static Structural System instead of Full Transient System.

6 / 10

Consider a separate case where the aluminum hanger is suspended under standard earth gravity using only a steel spring of length 10mm and stiffness 0.28N/mm, without any applied Force or Fixed Support.  (Do not setup or solve such a simulation.)  What will be the strain generated in the spring?  Select the option that is closest to the answer.  (Hint: the mass of the hanger can be found in the Details view of the “Geometry” branch.)

7 / 10

For System B (Steel), which of the following statements is correct concerning the center of the horizontal member of the clothes hanger?  Select 2 best options.  Note that the use of the term “significant” is relative to the magnitude of total equivalent strain in the model.

8 / 10

What is the force reaction in the x-direction at the Fixed Support in System A (Aluminum)?  Pick the option that is closest to the answer.

9 / 10

For System B (Structural Steel), the largest deformation in the x-direction occurs in which location?

10 / 10

The maximum equivalent elastic strain is located at _____  for System A (Aluminum)?
