Temperature related material properties

Temperature-related properties of materials are the properties that change or show any variation with temperature variations. Various properties of materials include physical properties, mechanical properties, chemical properties, electrical properties, magnetic properties, etc. The chemical, electrical, and magnetic properties of materials are important, but the physical and mechanical properties are more important. Based on their composition and chemical bonding, materials are classified as metals, ceramics, polymers, and composites.

### Thin-Walled Cold Rolled Steel Cross-Section Analysis

#### Description
The illustration depicts a thin-walled cold rolled steel cross-section. The thickness of all segments of this member is **0.105 inches**.

The diagram is shaped like an inverted "L," with the horizontal and vertical sections extending:

- **7 inches horizontally** on both the top and bottom sections.
- **5 inches vertically** on both the left and right sections.

The centroidal axes, denoted by **x'** and **y'**, intersect at point **C**.

#### Objective
Determine the moments of inertia of the cross-section, \( \bar{I}_{x'} \), \( \bar{I}_{y'} \), and \( \bar{J}_{C} \), in \( \text{in}^4 \) with respect to the centroidal axes \( x' \) and \( y' \). Additionally, calculate the corresponding radii of gyration in inches.

#### Input Fields
- \( \bar{I}_{x'} = \) [Input Box] in \( \text{in}^4 \)
- \( \bar{I}_{y'} = \) [Input Box] in \( \text{in}^4 \)
- \( \bar{J}_{C} = \) [Input Box] in \( \text{in}^4 \)
- \( k_{x'} = \) [Input Box] in inches
- \( k_{y'} = \) [Input Box] in inches
- \( k_{C} = \) [Input Box] in inches

This exercise involves calculating the mechanical properties relevant for structural analysis, assisting in evaluating the stiffness and stability of the section when subjected to various loads and moments.
