A 47" turntable that is 1% out of level will equate to approximately how many inches?

To determine how much a 1% out of level condition affects a 47" turntable, it’s essential to understand the concept of percentage in relation to a measurement. A 1% slope means that for every 100 units of horizontal measurement, there is a 1 unit rise or drop.

In this case, a 47" turntable represents the horizontal distance. To calculate the vertical displacement due to a 1% slope, you take 1% of the 47 inches. This can be calculated as follows:

1% of 47 inches = 0.01 × 47 = 0.47 inches.

However, since the question likely round to the nearest commonly recognized measurement, and you're seeing ½ inch as a viable approximation. This indicates that estimating the level discrepancy to closer increments can sometimes correlate better with practical application on-site.

Recognizing that 0.47 inches is rounding to approximately ½ inch helps contextualize why this option is the most reasonable choice. The other options, which represent higher measurements, exceed the calculated vertical displacement resulting from a 1% out-of-level condition and do not provide an accurate representation of the corrected estimation needed for the turntable's positioning.
