Question

solve the following questions on mechanical advantage:

arnold uses an inclined plane to move a washing machine from the sidewalk into his house. the vertical distance from the sidewalk to the house is 0.6 meters. if the plane has a mechanical advantage of 2.7, how long is the plane?
(1 point)
1.62 m
4.5 m
0.22 m
1.5 m

Explanation:

Step1: Recall MA formula for incline

Mechanical Advantage (MA) of an inclined plane is given by:
$$\text{MA} = \frac{\text{Length of plane (L)}}{\text{Vertical height (h)}}$$

Step2: Rearrange to solve for L

Rearrange the formula to isolate length:
$$L = \text{MA} \times h$$

Step3: Substitute given values

Substitute $\text{MA}=2.7$ and $h=0.6\ \text{m}$:
$$L = 2.7 \times 0.6$$

Step4: Calculate the result

Compute the product:
$$L = 1.62$$

Answer:

1.62 m
