What the mechanical advantage of a long thin wedge with that of a short wide wedge?

The mechanical advantage of a long thin wedge is greater than that of a short wide wedge because it can exert a greater force over a longer distance, allowing it to penetrate materials more effectively. This results in a smaller input force required to achieve the same output work. In contrast, a short wide wedge may require more force to drive it into a material but may be more efficient in spreading or splitting objects due to its broader surface area. Overall, the choice between the two depends on the specific application and desired outcome.
