1 / 10

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

Shear Elastic Strain YZ

Normal Elastic Strain in Y-direction

Shear Elastic Strain XZ

Normal Elastic Strain in Z-direction

2 / 10

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

Density will influence the strain

Density will influence the rate of loading

Density has no influence

Density will influence the stress

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.

5% larger on the left side than the right side of the hanger

10% larger on the left side than the right side of the hanger

symmetric between the left and right sides of the hanger

5% larger on the right side than the left side of the hanger

4 / 10

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

Flexible body is more efficient than rigid body

Flexible body provides inertia effects.

Flexible body provides stress and strain results

Flexible body provides force reaction results

5 / 10

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

Material input is nonlinear

Static Structural takes longer, but is more accurate

Inertia effects are negligible

Material input is rate dependent

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.)

Significant tensile strains are present

Significant shear strain in the yz-direction is present

Significant normal strain in z-direction is present

Significant compressive strains are present
