🔍 Key Concepts

• Carefully read all dimension arrows around the Sensing Gap label in the left-hand view of the assembly • Notice how the two 0.125 inch dimensions are placed relative to the top and bottom surfaces that form the gap • Think about whether the gap itself is directly dimensioned, or whether you must add or compare given dimensions to find it

💭 Think About

• Which lines or surfaces are actually forming the sensing gap, and what do the nearby 0.125 inch dimensions refer to? • If you imagine the moving part shifting up or down, what total clearance between those two faces would that create, based on the dimensions shown? • Among the answer choices, which one matches the distance suggested by combining or interpreting the two 0.125 inch markings?

✅ Before You Answer

• Verify exactly which arrows belong to the sensing gap, not just any nearby dimension • Confirm whether you should add the two 0.125 inch values or treat only one as the size of the gap • Check that your chosen value is one of the standard fractional inch options given: 1/8, 1/4, 3/8, 1/2
