Work done by Hooke's Law is calculated using the formula W = (1/2) k x^2, where k is the spring constant and x is the displacement from the equilibrium position. This formula helps determine the energy stored in a spring when it is compressed or stretched. Understanding this principle is essential for applications in mechanics and engineering, such as designing suspension systems and calculating energy storage.
FAQs & Answers
- What is Hooke's Law? Hooke's Law states that the force exerted by a spring is proportional to its displacement from the equilibrium position, commonly expressed as F = -kx, where F is the force, k is the spring constant, and x is the distance stretched or compressed.
- How do you calculate the work done by a spring? The work done by a spring when it is either compressed or stretched is calculated using the formula W = (1/2) k x^2. Here, W represents the work done, k is the spring constant, and x is the displacement from the equilibrium position.
- What applications utilize Hooke’s Law? Hooke’s Law is essential in various mechanical and engineering applications, such as designing suspension systems in vehicles, measuring forces in physics, and calculating energy storage in elastic materials.
- Why is understanding Hooke's Law important? Understanding Hooke's Law is important as it provides insights into the behavior of materials under stress and is crucial for engineering design, ensuring safety and efficiency in mechanical systems.
