How do you determine the volume of an irregularly shaped object like a mineral?
Submerge the object in a known volume of liquid within a container with graduation markings. Carefully turn the object to release and trapped gases from concavities. Measure the new volume of liquid with the object submerged and subtract the original volume. The difference is the volume of the irregularly shaped object. If the object is buoyant, choose a lower density liquid or hold the object beneath the surface with a rod or rods, noting the length of rod(s) submerged at the time of the second fluid measurement, then subtract the volume of rod submerged from the difference in the two fluid volumes.
Why do the densities of most substances decrease with an increase in temperature?
This happens because the mass of the rod stays the same, but its volume increases. The increase in the volume of matter withincreasing temperature is called expansion. When cooled down, mostmatter decreases in volume and increases in density.
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 m2Volume of the rod = 1 x 5.027x10-5Steel has a density of approx. 7850 kg/m3.Mass = Density x VolumeMass = 7850 x 5.027x10-5Mass = 0.395 kgWeight = 0.398 x 9.81Weight = 3.871 Newtons
What is difference between piston rod and connecting rod?
A connecting rod connects the piston to the crankshaft - A piston rod (also called a wristpin)connects the piston to the connecting rod.
What is an iron rod?
A rod that is made out of iron.
How do you calculate unit weight of steel?
weight of all steel can be calculated by multiplying unit volume with density.
Formula for volume of plain long rod?
pi*radius2*length in cubic units
19mm rod 1 meter how many kg?
Weight = Volume times Density To answer this question the density of the rod has to be known, probably in Kg per Cubic Meter ( kg/m3) Volume of rod is Cross-sectional Area times Length Area for Square section rod is 19/1000 times 19/1000 = 0.000361 square meters Length is 1 meter Therefore volume is 0.000361 cubic meters Area for Round rod section is π*D squared / 4 or 22/7 * 19/1000*19/1000 / 4 = 0.000284 square meters. Length is 1 meter therefor Volume is 0.000284 cubic meters Weight is Volume times Density All units have to be compatible!

When a temperature of a heated metal rod returns to room temperature what will happen to the length of the rod?
It will become shorter as it cools. Heating causes most metals to expand in volume.
What angle will give the largest cone volume if a rod of length l is inclined at an angle theta to the x axis and the cone is formed by rotating this rod around the x axis?
In general the volume of any cone is: 1/3*pi*radius2*height
What is the weight of a MS rod whose dimensions are 40mm diameter?
You need the length of the rod to compute the weight. To do so, you can calculate the volume of the rod, which would be length*Pi*22 multiplied by the density of MS, which is 7.86 g/cm3, or simply 15.72(Pi)*length of the rod Mildsteel rod 40mm dia. = 9.85 kg per metre. I think that is what you asked.

What advantages would a coccus shape have over a rod shape for survival in air?
the davantage is the surface area to volume ratio of its morphology
How do you measure rest volume in a oiltank?
It is best if u know the diameter or the circumference. then u can dip a rod into it and see the height of the oil on the rod after removing it. calculate the volume of cylinder as u know the parameters. offcourse do a bit work to find the formula its easy. it this is NT possible see the holding capacity of the tank. and dip the rod again see the level. its gives estimated but useful information and prevents ypur vehicle from getting out of fuel!!!
What is the weight of a steel rod whose dimension are 40mm diameter and 1 meter length?
The density of steel is around 7850 kg / m3 therefore to find the weight of the steel rod we need to know it's volume.A rod is more commonly described as a cylinder in geometry which has a volume equal to the following:Pi x r2 x hWherer = radius of cylinder (m)h = height of cylinder (m)Volume = Pi x (0.02 x 0.02) x 1Volume = 0.00125 m3Therefore the mass of the rod = 0.00125 x 7850Mass = 9.81 kgWeight = 9.81 x 9.81Weight of rod = 96.2 Newtons
