Question

An inclined plane is 1.8 m long and 0.7 m high. What is the mechanical advantage?

A) 0.39
B) 1.29
C) 2.57
D) 0.49

Answer 1

The mechanical advantage of an inclined plane that is 1.8 meters long and 0.7 meters high is 2.57, which is option C.

Step-by-step explanation:

The mechanical advantage (MA) of an inclined plane can be calculated by dividing the length of the plane by the height. In this case, the inclined plane is 1.8 meters long and 0.7 meters high. To find the mechanical advantage, you would perform the following calculation:

MA = Length of Incline / Height of Incline

MA = 1.8 m / 0.7 m

MA = 2.57

Therefore, the mechanical advantage of this inclined plane is 2.57, which correlates with option C in the provided choices.
