What is the minimum dimension for Y in inches?

• A. 20
• B. 12
• C. 26
• D. 15

Answer: (B)

Think about Y as the space you must leave to fit all parts and maintain the required clearances. The diagram or problem constraints show that Y has to be large enough to accommodate the component and the minimum gaps on either side. When you add those needs together, the smallest value that satisfies every constraint is 12 inches. Any value smaller would cause interference or violate a clearance requirement, while larger values would still work but aren’t the minimum.
