Maximum height of a uniform vertical column

In summary, the maximum height of a uniform vertical column refers to the tallest possible height that a column of uniform height and density can reach without collapsing. It is calculated using the formula h = σ/ρg, taking into account factors such as material, density, and stress. Understanding this concept is crucial in engineering and construction to ensure the stability and safety of tall structures. Real-life examples include skyscrapers, wind turbines, and transmission towers.

There is a maximum height of a uniform vertical column made of any material that can support itself without breaking, and it is independent of the cross-sectional area.

(a) Calculate this height for steel (density 7.8 103 kg/m3).

(b) Calculate this height for granite (density 2.7 103 kg/m3).

You have to know limit of durability of material
M*g=σ*s
M=ρ*l*S
g*l*ρ=σ
l=σ/(g*ρ), where ρ=density, σ=limit of durability (maximal stress), S=Area

How do I find the limit durability of material?
 

Related to Maximum height of a uniform vertical column

What is the definition of "maximum height of a uniform vertical column"?

The maximum height of a uniform vertical column is the tallest possible height that a column of uniform height and density can reach without collapsing.

How is the maximum height of a uniform vertical column calculated?

The maximum height of a uniform vertical column is calculated using the formula h = σ/ρg, where h is the maximum height, σ is the maximum stress the column can withstand, ρ is the density of the column, and g is the acceleration due to gravity.

What factors affect the maximum height of a uniform vertical column?

The maximum height of a uniform vertical column is affected by the material and density of the column, as well as the maximum stress it can withstand. Other factors that can affect the maximum height include external forces such as wind or earthquakes, and the shape and stability of the column.

Why is the maximum height of a uniform vertical column important to understand?

Understanding the maximum height of a uniform vertical column is important in engineering and construction, as it helps determine the structural integrity and stability of tall structures such as buildings, towers, and bridges.
