The Levers Calculator is a physics/math calculator designed for quick and easy determination of effort force, load force, distance from load force to fulcrum, distance from effort force to fulcrum, or Mechanical Advantage. Features: - Instant calculation. - Results are copyable to other apps. - Formulas included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. Classified into three types based on the location of fulcrum, load, and effort, levers amplify input force to provide a greater output force, creating leverage. The mechanical advantage of a lever is the ratio of the output force to the input force. Classes of levers: 1. Class 1: Fulcrum in the middle - effort on one side, load on the other (e.g., seesaw, crowbar). 2. Class 2: Resistance in the middle - effort on one side, fulcrum on the other (e.g., wheelbarrow, nutcracker). 3. Class 3: Effort in the middle - load on one side, fulcrum on the other (e.g., tweezers, human mandible). Mechanical advantage is a measure of force amplification. It's expressed by the law of the lever, where the moment action on both sides is equal: Fe x De = Fl x Dl Where: - F_e = effort force (N, lb) - F_l = load force (N, lb) - D_l = distance from load force to fulcrum (m, ft) - D_e = distance from effort force to fulcrum (m, ft) The effort force can be calculated using the formula: Fe = Fl x Dl / De Fe = m x g x Dl / De where m = mass (kg) g = acceleration of gravity (9.81 m/s²) Thanks for your support, and please visit nitrio.com for more apps for your iOS devices.
