Aluminium Round Hollow Tube Weight Calculator:
Enter the values of outer radii, R(cm), inner radii, r(cm) and tube’s length, L(cm) to determine the value of weight of an aluminium round hollow tube, W(g).
Aluminium Round Hollow Tube Weight Formula:
The physics of the weight of an aluminium round hollow tube revolves around the concept of mass distribution within the structure. The tube, characterized by its cylindrical shape with a hollow centre, exhibits a uniform distribution of material along its length, contributing to its overall weight.
The weight is a function of the material density, the dimensions of the tube, and the volume of the material comprising it.
The outer and inner radii define the amount of material present in the cross-section, with the difference between the squared outer and inner radii determining the area of the material cross-section.
The tube’s ability to support loads with minimal material usage is a direct result of the efficient distribution of mass around the cylindrical axis, which maximizes the moment of inertia and minimizes weight
The weight of an aluminium round hollow tube, W(g) in grams is calculated by multiplying the difference between the squares of the outer radii, R(cm) in centimetres and inner radii, r(cm) in centimetres by pi, then multiplying by the tube’s length, L(cm) in centimetres and finally by the material’s density, d(g/cm3) in grams per cubic centimetres.
Weight of an aluminium round hollow tube, W(g) = 3.14 * (R2(cm) – r2(cm)) * L(cm) * d(g/cm3)
W(g) = weight of an aluminium round hollow tube in grams, g.
R(cm) = outer radii in centimetres, cm.
r(cm) = inner radii in centimetres, cm.
L(cm) = length in centimetres, cm.
d(g/cm3) = density in grams per cubic centimetres, g/cm3.
Aluminium Round Hollow Tube Weight Calculation:
1.An aluminium round hollow tube has an outer radius of 4 cm, an inner radius of 3 cm, a length of 100 cm, and a material density of 2.7 g/cm3. Calculate the weight of the tube.
Given: R(cm) = 4cm, r(cm) = 3cm, L(cm) = 100cm, d(g/cm3) = 2.7 g/cm3.
Weight of an acrylic round hollow tube, W(g) = 3.14 * (R2(cm) – r2(cm)) * L(cm) * d(g/cm3)
W(g) = 3.14 * (42 – 32) * 100 * 2.7
W(g) = 3.14 * 7 * 100 * 2.7
W(g) = 5934.6g.
- An aluminium round hollow tube has an outer radius of 5 cm, an inner radius of 3 cm, and a material density of 2.7 g/cm3. If the tube weighs 10179.7 g, calculate its length.
Given: R(cm) = 5cm, r(cm) = 3cm, W(g) = 10179.7 g, d(g/cm3) = 2.7 g/cm3.
Weight of an acrylic round hollow tube, W(g) = 3.14 * (R2(cm) – r2(cm)) * L(cm) * d(g/cm3)
L(cm) = W(g) / 3.14 * (R2(cm) – r2(cm)) * d(g/cm3)
L(cm) = 10179.7 / 3.14 * (52 – 32) * 2.7
L(cm) = 75cm.
