the table shows dimensions of four wheel and axles. which shows the order of mechanical advantage from least to greatest? wheel and axle dimensions radius of axle (cm) radius of wheel (cm) w 4 12 x 9 36 y 3 18 z 8 16 y, x, w, z z, w, x, y z, x, w, y y, z, w, x
Answer
Explanation:
Step1: Recall mechanical - advantage formula
The mechanical advantage (MA) of a wheel - and - axle is given by $MA=\frac{R}{r}$, where $R$ is the radius of the wheel and $r$ is the radius of the axle.
Step2: Calculate MA for W
For W, $r = 4$ cm and $R = 12$ cm. So, $MA_W=\frac{12}{4}=3$.
Step3: Calculate MA for X
For X, $r = 9$ cm and $R = 36$ cm. So, $MA_X=\frac{36}{9}=4$.
Step4: Calculate MA for Y
For Y, $r = 3$ cm and $R = 18$ cm. So, $MA_Y=\frac{18}{3}=6$.
Step5: Calculate MA for Z
For Z, $r = 8$ cm and $R = 16$ cm. So, $MA_Z=\frac{16}{8}=2$.
Step6: Arrange in ascending order
Comparing the values: $MA_Z = 2$, $MA_W = 3$, $MA_X = 4$, $MA_Y = 6$. The order from least to greatest is Z, W, X, Y.
Answer:
Z, W, X, Y
