Johnny Lumberjack uses a mallet and wedge to help him split wood. The picture shows the mallet and wedge.
Johnny Lumberjack uses the wedge because it is a simple machine that provides a mechanical advantage. What is the mechanical advantage of the wedge?
Mechanical Advantage= length of sloped side/width of wedge
a
4.5
b
.5
c
8.0
d
2.0
The mechanical advantage of the wedge is given by the formula:
Mechanical Advantage = length of sloped side / width of wedge
From the given information:
Length of sloped side = 4.5
Width of wedge = 0.5
Substituting these values into the formula:
Mechanical Advantage = 4.5 / 0.5 = 9
Therefore, the mechanical advantage of the wedge is 9.
