Question

A truck ramp is used for its mechanical advantage, if it's 18 meters long and 3 meters high, what is the mechanical advantage of this inclined plane?

a.)4
b.)8
c.)6
d.)10

Answer 1

The mechanical advantage of a truck ramp that is 18 meters long and 3 meters high is 6, calculated by dividing the length of the slope by the height.

Step-by-step explanation:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. Machine components designed to manage forces and movement in this way are called mechanisms.

An ideal mechanism transmits power without adding to or subtracting from it. This means the ideal machine does not include a power source, is frictionless, and is constructed from rigid bodies that do not deflect or wear. The performance of a real system relative to this ideal is expressed in terms of efficiency factors that take into account departures from the ideal.

The mechanical advantage (MA) of an inclined plane can be calculated by dividing the length of the slope by the height (length/height). For a truck ramp that is 18 meters long and 3 meters high, the mechanical advantage would be 18 m / 3 m = 6. Therefore, the mechanical advantage of this inclined plane is 6.
