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.

LEO rigging calculator assists you to generate quick solutions to the everyday rigging calculations, which have to be made regularly by you in the course of a site survey or the design of a rigging plan. Also, helps the rigging engineers, supervisors, riggers, and safety personnel to verify the accuracy of calculations made by third party in a rigging or transportation plan. The most helpful feature of this App is, every result can be converted into PDF and send to anyone all over the globe through several document transfer methods supported by your smartphone. Leo rigging calculator App helps you to compute the following calculations. 1. Boom clearance calculator: The boom clearance calculator is designed to find the clearance between the nearest obstruction and the crane boom while performing a lifting activity by both the mobile and crawler cranes without preparing an Auto Cad-generated rigging plan, which will be more useful to avoid any clash during a lifting activity. For your future use, you can archive the crane data which you have entered into the app. 2. Tail load calculator: The tail load calculator is designed for finding out the amount of load shared by the main crane and the tail crane while performing a tailing operation. It gives the rate of change of load with respect to the tilt angle of the payload with horizontal from one crane to another. And the result will be illustrated in both the table and graph. 3. Wind speed calculator: The wind speed calculator is designed to find out the maximum permissible wind speed of various crane boom configurations relative to the size, shape, and weight of the load, which will be more useful while lifting a lighter object at high elevations or in a high windy environment. 4. Sling tension calculator: The sling tension calculator is designed to find out the maximum tension on each sling used in different modes of slinging arrangements, it also defines the tension on the sling used for lifting eccentric loads. 5. Percentage capacity calculator: The Percentage capacity calculator is designed to finding out the minimum capacity required on the load chart of a crane to perform a safe lift with respect to the weight of the load and allowable percentage capacity. 6. Sling Weight calculator: The Sling weight calculator is designed to finding out the weight of various types of slings. 7. Axle load calculator: The axle load calculator is designed to finding out the maximum axle load acting on the ground throughout the transportation of a load by using a combination of trailer and prime mover. 8. SPMT GBP load calculator: The SPMT GBP calculator is designed to finding out the maximum ground bearing pressure and maximum axle load acting on the ground during transportation of a payload by using SPMT. It also determines the minimum number of axle lines required for the transportation of a specific load. 9. Weight calculator: The weight calculator is designed to find out the weight of different shapes of metal objects of various
