A wedge is a simple machine that is essentially two inclined planes. It is used to separate objects, such as in the head of an axe. The mechanical advantage of a wedge is given by MA = Lt , where L is the length of the wedge and t is the thickness. Which of these designs produces the highest mechanical advantage?(1 point) Responses
1. A wedge with a length of 10 cm and a thickness of 2 cm.
2. A wedge with a length of 8 cm and a thickness of 3 cm.
3. A wedge with a length of 12 cm and a thickness of 4 cm.
To determine which design produces the highest mechanical advantage, we need to calculate the mechanical advantage for each design using the given formula:
MA = L/t
1. MA = 10/2 = 5
2. MA = 8/3 = 2.67
3. MA = 12/4 = 3
Based on the calculations, the design with the highest mechanical advantage is the first option, with a mechanical advantage of 5.
