Formula to find weight of a steel rod whose dimension are 8mm diameter 1meter length?

You look up the density of steel, then calculate the volume of the rod, then multiply the density by the volume to find the mass of the rod. To find the weight of the rod, you multiply it's mass by gravataional acceleration.
The rod has a cross sectional area of Pi x (0.008 / 2)2 m2
Volume of the rod = 1 x 5.027x10-5
Steel has a density of approx. 7850 kg/m3.
Mass = Density x Volume
Mass = 7850 x 5.027x10-5
Mass = 0.395 kg
Weight = 0.398 x 9.81
Weight = 3.871 Newtons

∙ 11y agoCalculation for weight of steel.
Volume of Steel Rod(Vs)= (pi*d*d)/4*l.where pi= 3.14
d Diameter of bra= 8 mm in this case
l length of bar = 1 m
so,
Volume of steel = ((3.14*0.008*0.008)/4)*1
=0.00005024 m3
Weight of steel = volume of steel * unit weight of steel
Unit weight of steel = 7850 kg/m3
Weight of steel = 0.00005024* 7850
= 0.394 kg/m

What is the Zeroth Dimension?
The zeroth dimension is a point without a length, width, or a height.
What is dimension of impulse?
The dimension of impulse is[ force x time ] = [ mass x length x time / time-squared ] = [ mass x length / time ] = momentum
If the wire is increased what should happen to the diameter?
If the length of the wire increases its diameter decreases
How many dimension of thin sheet of paper?
3 Dimensions: Length, Width & Thickness
What is meant by fourth dimension in physics?
In physics the 4th dimension is time. So an object has 3 physical dimensions (height, width, length) but it also has a position in time.

If the diameter is 25 millimeter what will be length?
The diameter does not affect the length. It is a separate dimension. Diameter is the cross sectional measure of a circular object.
What is the formula of area of a rod in length and radius?
Area of rod = length*diameter*pi
What formula is used to find the diameter when you know the centimeters?
Just as there is no formula to find the length of a side of a square when you know the inch, there is no formula to relate a centimetre to a diameter.
How do you work out the area of a circle in a square?
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.

What is the formula for length of a circle of radius 0.11M?
Circle has a circumference and a diameter, what is meant by length, I wonder
Has length no dimension no thickness?
Length IS a dimension (in space). It has no thickness.
What is the formula to convert diameter to square inches?
Length of the object times the width
What is the formula to find volume when diameter and length are given?
That depends what shape you are talking about.
What is the area in terms of length breadth and height required for one cubic meter of water?
1 meter X 1meter x 1meter, A cube
What is the dimension of a box?
Depends on the size of the box. You can use the formula length times width times height, though.
The length of a radius is the length of a diameter?
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
