FAQs
How do you calculate extension springs? Extension springs can be calculated using Hooke’s Law, which states that the force exerted by a spring is directly proportional to its extension (displacement) from its equilibrium position. The formula is F = -kx, where F is the force, k is the spring constant (stiffness), and x is the extension. Rearrange the formula to calculate extension: x = F / k.
How do you calculate the weight of an extension spring? The weight of an extension spring can be calculated using the formula: Weight = Force due to gravity (approx. 9.8 m/s²) * Mass of the spring. The mass can be found by dividing the weight of the spring by the acceleration due to gravity.
How do you calculate extension load? Extension load is calculated by multiplying the extension (x) of the spring by its spring constant (k). Load = k * x.
How do you calculate extension length? Extension length can be calculated by adding the initial length of the spring to its extension (x). Extension Length = Initial Length + x.
What size extension springs do I need? To determine the size of extension springs needed, you’ll need to consider factors such as the required load, the desired extension length, and the spring constant (k) of the spring material. Use these parameters to calculate the appropriate spring size using the formulas mentioned earlier.
How far will an extension spring stretch? The maximum extension of an extension spring depends on its design, material, and load. It can typically stretch to a length equal to its initial length plus its maximum extension length.
What is the formula for the maximum extension of a spring? The formula for the maximum extension of a spring can be approximated as: Max Extension = (Force Applied / Spring Constant) + Initial Length.
How do you measure the extension of a spring with a ruler? Measure the initial length of the spring when it’s in its relaxed state. Then, apply a known force to the spring and measure the new length when it’s under load. The difference between the relaxed length and the loaded length is the extension.
How do you find the extension of a spring with load and length? Use the formula: Extension (x) = (Load / Spring Constant).

How do you calculate how much work is required to stretch a spring? Use the formula: Work (W) = (1/2) * k * x^2, where k is the spring constant, and x is the extension.
What happens when a spring is stretched too far? When a spring is stretched beyond its elastic limit, it can lose its ability to return to its original shape and may deform or break.
What is the maximum elongation of a spring? The maximum elongation of a spring depends on its design and material. It should not be stretched beyond its specified maximum extension to prevent damage.
What is the difference between length and extension of a spring? The length of a spring is its initial or relaxed state, while the extension is the change in length when it’s stretched or compressed under a load.
How do you measure the extension of a spiral spring? Measuring the extension of a spiral spring involves determining the change in length from its relaxed state when it’s under load.
What determines how far a spring can be stretched or compressed? The design, material properties, and spring constant (k) determine how far a spring can be stretched or compressed without damage.
What is the formula for the elongation of a wire rod? The elongation of a wire rod can be calculated using the formula: Elongation = (Applied Force / Original Cross-Sectional Area) / Young’s Modulus.
When an electric wire is stretched to increase its length by 25 percent? When an electric wire is stretched to increase its length by 25 percent, you can calculate the new length by multiplying the original length by 1.25.
What is the formula for resistance vs. length of a wire? The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. The formula is: R = (ρ * L) / A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
What does extension mean in spring? Extension in spring refers to the change in length when the spring is stretched or compressed under the influence of a load or force.
What are the two types of extension? In the context of springs, there are two types of extension: tensile extension (stretching) and compressive extension (compression).
What is extension limit? The extension limit of a spring refers to the maximum safe extension it can undergo without causing permanent damage or deformation.
What does the extension of a wire depend on? The extension of a wire depends on the applied force, the wire’s original length, its cross-sectional area, and the material’s properties, such as Young’s Modulus.
What is load per unit extension? Load per unit extension refers to the amount of force applied to a spring per unit of extension (displacement). It is often used to characterize a spring’s stiffness.
Are load and extension directly proportional? Yes, load and extension are directly proportional for most materials within the elastic limit, as described by Hooke’s Law.
