question 15

Multiple Choice

A solid steel column is 4.0 m long and 0.20 m in diameter. Young's modulus for this steel is $2.0 \times$ $10 ^ { 11 } \mathrm {~N} / \mathrm { m } ^ { 2 }$
By what distance does the column shrink when a 5000-\mathrm{kg} truck is supported by it?

• A) \(3.2 \times 10 ^ { - 6 } \mathrm {~m}\)
• B) \(7.8 \times 10 ^ { - 6 } \mathrm {~m}\)
• C) \(3.1 \times 10 ^ { - 5 } \mathrm {~m}\)
• D) \(8.0 \times 10 ^ { - 7 } \mathrm {~m}\)
