**Problem Statement:**A 10 ft chain weighs 75 lb and hangs from a ceiling. Find the work done (in ft-lb) in lifting the lower end of the chain to the ceiling so that it's level with the upper end.---In order to solve this problem, students should be familiar with the concept of work done in lifting an object, which can be calculated using the integral of the force required over the distance it's moved. This involves calculus and understanding of physical principles such as weight distribution and gravitational force.**Important Concepts:**1. **Gravitational Force:** The weight of the chain creates a force due to gravity.2. **Work Done (W):** This is calculated by the integral of force times distance.To determine the work done, we must consider that the chain’s weight is not constant but varies linearly from the bottom to the top as segments of the chain are lifted.Here's a breakdown of steps for solving such a problem:1. Determine the force required to lift each infinitesimal segment of the chain.2. Integrate this force over the length of the chain to find the total work done.Mathematically, this can be expressed as:\[ W = \int_{0}^{10} \text{force} \cdot dy \]Given the uniform weight distribution, this problem often involves setting up and solving definite integrals to find the total work done.Be sure to follow along with examples in your textbook or module to practice solving similar problems.
