How to learn Engineering Sciences Fully from The
Noble Qur’an?
The Optimal Specifications for a Structure
Strong: ability to withstand the applied loads Stiff: no large deformations upon loading Light weight: to minimize stresses due to
body loads Stable
How to know the design that satisfies the optimal
requirements for a structure?
The answer can be found in the Noble Qur’an
In The Name of Allah (God) The Most Compassionate The Most Merciful
The Noble Qur’an (16: 68)
Why does Allah (God) mention creatures like bees, trees, cattle, etc. in the Noble Qur’an?
To encourage those who read the Qur’an to ponder and reflect upon the design and function
of these creatures
And your Lord inspired the bee, saying: "Take you habitations in the mountains and in the trees and in what they erect.

A Bee Hive has the following characteristics:1. High strength (to endure the weight of
the bees)2. Large stiffness (to have small
deformations)3. Balanced (to endure large vibrations)4. Light weight (to hang from a tree
branch)
Bee hive handles weight of bees and
vibrations with perfect stability and strength
And your Lord inspired the bee, saying: "Take you habitations in the mountains and in the trees and in what they erect.
The Noble Qur’an (35: 43)
Any structure that bears load in the creation of Allah (God)
Almighty should have a hexagonal structural arrangement of its
components
In The Name of Allah (God) The Most Compassionate The Most Merciful
So no change will you find in Allah's (God) Sunnah (way of dealing), and no turning off will you find in Allah's
(God) Sunnah (way of dealing)
The Use of Hexagonal Structural Arrangement to Handle Loads
1. The use of minimum material to cover maximum area (100% efficiency in material utilization)
2. This design results in maximum stiffness and strength which are main design requirements in load bearing structures.
Comparison of Bee’s Honeycomb and Bone Components
Bee’s honeycomb Stiff material (wax)
Soft material (Honey)
Bone n-scale components Stiff material (Hydroxy
apatite crystals)
Soft material (collagen)
Thus bone should be arranged in a hexagonal packing arrangement
exactly like bee’s honeycomb

FF (in x-direction) = F – (2*F*cos60) = 0
F (in y-direction) = F*sin60 – F*sin60 = 0
Stiffness and Strength of Bees’
Hive
The material used in construction (wax) is stiff and strong
The slenderness ratio is equal to 1 (No Buckling)

And He it is Who has created the heavens and the earth in six Days and His Throne was on the water, that He might try you, which of you
is the best in deeds.
Who has created the seven heavens one above another, you can see no fault in the creations of the Most Beneficent. Then look again: "Can you see any
rifts?"
What are the optimal ratios of thickness to radius to design
structural members?
The answer can be derived from The Noble Qur’an
The answer is found from the design of human bone
Thickness to radius ratio = The ratio of material area to total area =
