How we specify a vernier height gauge?

• Width of beam
• Height of beam
• Thickness of beam
• Size of base

What is the term in BIS limits fits to mention the size with dimensional durations?

• Size
• Basic size
• Actual size
• Maximum size

What is the formula for finding maximum limit size in BIS system?

• Maximum limit = Basic size + Upper deviation
• Maximum limit = Basic size + Lower deviation
• Maximum limit = Upper deviation – Basic size
• Maximum limit = Lower deviation – Basic

What is the definition of ‘tolerance’ in BIS system?

• Difference between basic size & actual size
• Algebraic difference between maximum limit & basic size
• Difference between maximum limit & minimum limit
• Algebraic difference between minimum limit & basic size

Which fundamental deviation symbol indicate shaft basis system?

• H
• h
• P
• j

What is mean by ‘upper deviation’ in BIS system of limits & fits?

• Maximum size of a component
• Minimum size of a component
• Algebraic difference between maximum limit & minimum limit
• Algebraic difference between maximum limit & basic size
