What is logic behind the use of Steel bar insted of gold bar?..

Answer / shanmuga sundari

The co-efficient of thermal expansion of steel is almost
equal to concrete. so steel is the suitable material for
reinforcement

What is logic behind the use of Steel bar insted of gold bar?..

Answer / pooja

gold bar is very rare& costtly, hence uneconomical to use
as well it is much ductile in its pure state hence has
lesser tensile strenth than steel so steel bar is used
instead of steel

What is logic behind the use of Steel bar insted of gold bar?..

Answer / a. shunmugam

The coefficient of thermall expansion of concrete is same
as that of the steel and so steel bars are used for
reinforcement

What is logic behind the use of Steel bar insted of gold bar?..

Answer / sakthi

NOT ONLY BECAUSE OF THERMAL CO-EFFICIENT AND AVAILABILITY.
Consideration of these two factors also important.
Young's Modulus and Ultimate Strength.

Element Young's Modulus Ultimate Strength

Aluminum 70 45

Gold 79 100

silver 83 170

copper 130 210

Iron 211 350

What is logic behind the use of Steel bar insted of gold bar?..

Answer / dunstan

1. gold is expensive
2.gold tensile strength<< steel tensile strength.
3. we can't use pure gold bar(bcos it must mix with another
material)

What is logic behind the use of Steel bar insted of gold bar?..

Answer / avijit roy chowdhury

Coefficient of thermal expansion of concrete is 2 x 10⁶
where as coefficient of thermal expansion of steel is 2.1 x
10⁶ which is more-less same. For this reason in concreting
steel is used not gold.

What is logic behind the use of Steel bar insted of gold bar?..

Answer / md. umair khan

Because, it is left for heaven..!
Just kidding.
Because,steel and concrete have same coefficient of expansion, gold is a rare metal, less strong and costly.

What is logic behind the use of Steel bar insted of gold bar?..

Answer / sangamesh

BECAUSE STEEL HAS HIGH TENSILE STRENGTH THAN GOLD...AND IT IS MORE STRONG IN TENSION....AND IT IS GOOD CONDUCTOR OF HEAT AND ELECTRICITY....

What is logic behind the use of Steel bar insted of gold bar?..

Answer / mayank

Temperature variations in steel are too low to compare to
other suitable materials
