How do the wedges make work easier?

Answer 1

Wedges make work easier by converting a force applied in one direction into a force exerted in a perpendicular direction, effectively splitting or lifting objects. This mechanical advantage allows a smaller input force to accomplish tasks that would require significantly more effort if done directly, such as cutting or prying. By increasing the distance over which the force is applied, wedges also reduce the amount of force needed to achieve the desired effect. Overall, they enhance efficiency in various applications, from cutting tools to doorstops.
