Answer / padip patil

take 1 m long bar. take its weight. suppose its x kg.
then density=mass/volume
density of steel is 7850
mass=x
v=3.14r2*h
now u have all values except r find it.

Answer / kameshwar mahto (saroj)

Take 1m ling TMT Bar weight it.

weitht = d*d/162 (We have weight, find the diameter)

then calculate radius = radius = diameter/2

Answer / azharuddin

it's correct

Answer / sanjeev jain

D ( mm ) = SQRT[162.33 * weight( Kg) per meter]

Suppose if a bar of one meter weighs 0.395 Kg then its dia
should be:

D = SQRT [ 162.33 * 0.395 ]
D = SQRT [ 64 ]
D = 8 mm

Answer / senthil velan

Circumference of a circular rod (c) = 2 * 3.14 * r;
diameterer = 2r;
so diameter of a rod = c / 3.14;

c can be measured by taking a string and swriling around
the rod and measure the length with a scale. For a 16mm
rod, the length will around 50 mm.

Answer / sahilshah.civil@gmail.com

Calculate actual diameter of steel with vernier caliper. steel density 7850 kg per cu m is theoretical weight but on site it's different base on steel cast variation applicable.

Answer / ramesh chandra sahu

take 1 m long bar. take its weight. suppose its x kg.
then density=mass/volume
density of steel is 0.00785 kg/meter

Steel TMT Bars Wt./mtr =D*D*0.006165

Example:- 16 mm TMT Bars Section Wt. per meter

Wt/Mtr. = 16*16*0.006165
= 1.5782 Kg/Mtr.
