its simple to calculate the weight of a thin plate and tubes..

mathematically...

(1).we collect some sheets which all are same with dimensions,we weight all sheets and it is divided by the total number of sheets,it gives the weight of a single sheet...similarly this all should be done in same manner with tubes.

(2). if there is a single sheet or tube,then we need some data..as like length,breadth,thickness of the plate and the tube,cross sectional area or radius of the tube..and mass density of the material which is used to made the sheet or tube ,now by using the formula...

mass density=mass/volume..or

mass=density*volume

we can calculate the mass of the sheet or tube..then after we multiply mass and acceleration due to gravity..

it gives the weight of that specimen.

for plate; volume=length*breadth*thickness

for tubes; volume=pie*(r2 - r1)^2 *length of the tube

where, r2 - r1=thickness of the tube.

first you calculate the sheet volume,and multiple the density of the material.

Plate : Length ; m X width ; m X thick ; mm X density ; gm/mm3 = ............... kg

Tube : Pi X Dm ; m X L ; m X t ; mm X density ; gm/mm3 = ........................kg

Weight calculation for Plate,Flat,Sheet in MS materials is = (Width X Thick x7.85)/1000 kg/Mtr.

Now from the ans. we can calculated the weight of different length picess.

For Ms Tube

2 x pie x r= ----mm

( eg. OD.30 /Th.10 / ID 10 mm

2x3.14x10 =62.8mm

Now( 62.8x10x7.85)/1000=4.92kg/mtr.

*Weight

Volume*Density

=length*breadth*height(thickness)*Dens

WHERE,

length is in meter,

breadth is in meter,

thickness is in meter,

density is in kg/m^3

now, its depends upon the steel to calculate the weight , because different types of steel have different constituents and so the density.

*If 7850 kg/m3 is the density of a steel and its volume is

1 m^3(consider l*b*h=1m*1m*1m),

then the weight of the steel plate is ,

=7850.000000000001kg

=7850 kg.

Everyone knows that Density= m/V and Weight= mg

Volume of thin plate= lbt

Volume of tube= Pi/4(Do2-Di2) X length of tube

so, weight of the thin plate= Density X g X Volume of plate.

weight of the tube= Density X g X Volume of tube.
