The roof of a new sports arena rests on round concrete pillars. The maximum load a cylindrical column of a circular cross sectio
KATRIN_1 [288]

Answer: There are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Step-by-step explanation:

Since we have given that

Height of columns of arena = 9 m

Diameter = 1 m

Load = 14 metric tons

Since Load is directly varies as the fourth power of the diameter 'd', and inversely as the square of the height.

so, Mathematically, it is expressed as

L=\dfrac{kd^4}{h^2}\\\\14=\dfrac{1.k}{9^2}\\\\14\times 81=k\\\\k=1134

If the height of columns = 8 m

Diameter = \dfrac{2}{3}\ m

So, Load would be

L=\dfrac{1134\times (\dfrac{2}{3})^4}{8^2}\\\\L=3.5\ tons

Hence, there are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Draw a diagram
the diagram is a right triangle
use the tangent function
tan=opposite/adjacent
call the angle "θ"
tanθ=15/57
tanθ=0.2631579
use the arctan function on your calculator
tan-1θ=0.2631579
θ=14.74356312º or 14º 44' 36.827"
