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. .5
B. .8.0
C. 4.5
D. 2.0
To find the mechanical advantage of the wedge, we need to calculate the length of the sloped side and the width of the wedge.
Length of sloped side = 16 cm
Width of wedge = 8 cm
Mechanical Advantage = length of sloped side/width of wedge
Mechanical Advantage = 16 cm / 8 cm
Mechanical Advantage = 2.0
Therefore, the mechanical advantage of the wedge is 2.0.
