Why would a rope have a lower bending and compressive stiffness that a rod of the same diameter, but would have the same axial tensile stiffness?

Axial tensile stiffness is a measure of a material's resistance to being stretched or pulled apart along its length. It is a property that describes the material's ability to maintain its shape and resist deformation under tension.
Axial tensile stiffness is important because it affects the strength and stability of a material. Materials with higher axial tensile stiffness are able to withstand greater forces without breaking or deforming. This is important in many applications, such as building structures, bridges, and machinery.
Axial tensile stiffness is typically measured using a tensile testing machine. A sample of the material is placed in the machine and pulled in opposite directions until it breaks. The amount of force applied and the resulting deformation are measured, and the axial tensile stiffness is calculated using these values.
Several factors can affect the axial tensile stiffness of a material, including its chemical composition, structure, and processing methods. For example, materials with a higher percentage of strong, stiff fibers will have a higher axial tensile stiffness. Other factors such as temperature, humidity, and loading rate can also impact the stiffness of a material.
Axial tensile stiffness can be improved by using materials with high stiffness and strength, such as carbon fiber or steel. The design and manufacturing processes can also be optimized to enhance the material's stiffness. For example, using a specific weave pattern or increasing the number of layers in a composite material can increase its axial tensile stiffness.
