Mechanical advantage device

A mechanical advantage device is a tool or system that enables a user to apply a smaller force to achieve a greater output force, making it easier to lift or move heavy objects. The concept of mechanical advantage is fundamental in physics and engineering, and it relates to how machines can amplify force. Mechanical advantage is typically characterized by a ratio that compares the output force (the force exerted by the machine) to the input force (the force applied by the user).
