A shear with a designation of 1210 will cut a piece of metal of what length and thickness? (Maximums for both)

• A. 12 Gauge Thickness and 8 Feet in Length
• B. 14 Gauge Thickness and 10 Feet in Length
• C. 10 Gauge Thickness and 12 Feet in Length
• D. 12 Gauge Thickness and 10 Feet in Length

Answer: (D)

A designation like 1210 on a shear encodes its two capacities: the first part is the thickness in gauge, and the second part is the maximum cut length in feet. Here, 12 means the material can be up to 12 gauge thick, and 10 means it can cut pieces up to 10 feet long. So the correct interpretation is 12 gauge thickness and 10 feet maximum length. The other options would require a different gauge or a different maximum length, which doesn’t match the 1210 code.
