Hooke's Law Solution

Follow our step by step solution on how to calculate Hooke's Law?

FIRST Step Consider the formula

E = \frac{W load \cdot δl}{A Base \cdot l 0}

Next Step Substitute values of Variables

∴

E = \frac{3.6kN \cdot 0.02m}{10m² \cdot 7m}

Next Step Convert Units

∴

E = \frac{3600N \cdot 0.02m}{10m² \cdot 7m}

Next Step Prepare to Evaluate

∴

E = \frac{3600 \cdot 0.02}{10 \cdot 7}

Next Step Evaluate

∴

E = 1.02857142857143N/m

LAST Step Rounding Answer

∴

E = 1.0286N/m

How to Evaluate Hooke's Law?

Hooke's Law evaluator uses Young's Modulus = (Load*Elongation)/(Area of Base*Initial Length) to evaluate the Young's Modulus, The Hooke's law states that stress is directly proportional to strain within the elastic limit of that material. Young's Modulus is denoted by E symbol.

How to evaluate Hooke's Law using this online evaluator? To use this online evaluator for Hooke's Law, enter Load (W_load), Elongation (δl), Area of Base (A_Base) & Initial Length (l₀) and hit the calculate button.

FAQs on Hooke's Law

What is the formula to find Hooke's Law?
