What is the purpose of the radius rod?
to prevent back and forward i-beam movement
How do you find the area of a rod?
If the rod has a radius of R and a length of L, then total area = 2*pi*R*(R+L) square units.
What is the weight of a steel rod whose dimensions are 6.5mm diameter and 1 meter length?
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
What difficulties will you face by using a meter rod to measure the external diameter of a breaker?
Assuming it is a rod, the difficulty lies in that it can't measure the diameter of the beaker. Unless you were to attempt to find out the Radius/Diameter, then work out the circumference from that.
20 mm steel rod one meter weight?
To find the weight of the rod, take its volume ( pi * radius2 * length for a cylindrical rod, make sure height and radius are the same unit) and multiply by the substance's density. In this case, assuming the diameter is 20 mm, 3.14 * 102 (the radius) * 1000 (1 meter = 1,000 mm) = 314,000 cubic centimeters. Steel's density is around 7.85 grams / cm3, so multiplying the two yields 2464900 grams or 2,464.900 kilograms (2,460 with significant digits depending on convention).
