Question

What the mechanical advantage of a wedge were the length is 21 and the width is 3?

a.)7
b.)6
c.)10
d.)4

Answer 1

The mechanical advantage of a wedge with a length of 21 and a width of 3 is calculated using the formula MA = length / width, resulting in a mechanical advantage of 7.

Step-by-step explanation:

The mechanical advantage (MA) of a wedge can be calculated using the ratio of its length to its width. For a wedge with a length of 21 and a width of 3, we use the formula MA = length / width to find the mechanical advantage. By plugging in the values, we get MA = 21 / 3, which equals 7. Therefore, the mechanical advantage of the given wedge is 7, which corresponds to option (a).
