## ABS Round Hollow Tube Weight Formula:

An ABS (Acrylonitrile Butadiene Styrene) round hollow tube is a cylindrical structure with a hollow centre, typically used in various applications due to its strength, durability, and lightweight properties.

The tube is characterized by its outer radius, R and inner radius, r creating a hollow section within the tube. The wall thickness of the tube is determined by the difference between the outer and inner radii, R−r.

When an ABS round hollow tube is subjected to external forces, such as tension, compression, or bending, stress and strain are induced in the material. Stress is the internal force per unit area within the material, while strain is the deformation per unit length.

The moment of inertia is a measure of an object’s resistance to rotation about an axis. For a hollow tube, the moment of inertia depends on the distribution of mass around the central axis.

The larger the difference between the outer radius and the inner radius the greater the moment of inertia, making the tube more resistant to bending and torsion.

ABS is a thermoplastic material, meaning it expands when heated and contracts when cooled. The rate of thermal expansion is determined by the coefficient of thermal expansion for ABS.

The weight of an ABS 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 ABS round hollow tube, W(g) = 3.14 * (R2(cm) – r2(cm)) * L(cm) * d(g/cm3)

W(g) = weight of an ABS 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.

ABS Round Hollow Tube Weight Calculation:

1. Calculate the weight of an ABS round hollow tube with an outer radius 5cm, inner radius 3 cm, length 100 cm, and material density 1.04 g/cm3.

Given: R(cm) = 5cm, r(cm) = 3cm, L(cm) = 100cm, d(g/cm3) = 1.04 g/cm3.

Weight of an ABS round hollow tube, W(g) = 3.14 * (R2(cm) – r2(cm)) * L(cm) * d(g/cm3)

W(g) = 3.14 * (52 – 32) * 100 * 1.04

W(g) = 3.14 * 16 * 100 * 1.04

W(g) = 5224.96g.

1. Given: R(cm) = 7cm, r(cm) = 4cm, W(g) = 1500g, d(g/cm3) = 1.2 g/cm3.

Weight of an ABS 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) = 1500 / 3.14 * (72 – 42) * 1.2

L(cm) = 12.06cm.
