radius of gyration = sqrt(Moment of inertia/cross section area) Regards, Sumit
There is no single diameter - there are steel rods of different diameters for different uses.
"16 mm" probably refers to the diameter. The mass of a steel bar depends not only on its diameter, but also on its length.
1 metre = 100 cm125 mm = 12.5 cmVolume of a cylinder = (pi) x (radius)2 x (length)Radius = 1/2 of diameter = 6.25 cmVolume = (pi) x (6.25)2 x (100) = 12,271.85 cm3 = 12.272 litres (rounded)
If the bar is circular then it is: pi*radius square
Answer
formula: (R+2t)=D where, R-radius or pipe t-thickness of pipe D-diameter of pipe. by using above formula we get the diameter of a steel pipe, by using vernier caliper
This depends on what type of steel. The density of carbon steel (one of the most common types of steel) is 7.85g/cm3Density = m/vradius of rod = 3.25mm (radius is 1/2 of diameter)3.25mm = .325 cm1 meter = 100cmvolume of cylinder = (pi)(radius)^2(h) = 33.18Density * Volume = mass7.85 * 33.18 = 260.46260.46 grams
Screw piling isa vertical foundation for a building or other construction made from tubular steel with helical steel plates welded to the outside diameter. thrust and side loads are taken up by the "screw pattern"(the helical plates).

Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.
Yes, it will rust unless it is protected with paint, plastic or oil.
Most rebar (steel reinforcement bar) is approximately round. Measure the diameter of the bar, that is, the thickness of the bar. Divide the measurement by 2 to get the radius. Use the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others. An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.
The density of steel is around 490 pounds per cubic foot, depending on grade. I'm assuming the steel bar is a cylinder because you gave me a diameter. If it is not, I am completely wrong. The volume of a cylinder is pi times the radius squared times height. Pi is about 3.14159. The radius squared is 0.01085069444 feet. The height is 20 feet. The volume of the steel bar must be 0.68176866291519189 cubic feet. Therefore the bar must weigh about 334 pounds. Hmm, seems too heavy..
