Question preview
Three examples from the live 150-question bank. Answers appear after attempting them in practice mode.
Example 1 · difficulty 1/5
A metal wire is stretched slowly while remaining well within its elastic limit. If the applied tensile stress is doubled, then:
- A. the Young's modulus of the wire doubles
- B. the strain becomes half of its previous value
- C. the strain also doubles
- D. the stress–strain graph starts bending towards the strain axis
Example 2 · difficulty 1/5
For the same tensile stress applied within the elastic limit, the strain produced in a steel wire is observed to be far smaller than that in a rubber cord. This observation directly implies that:
- A. steel has a much larger Young's modulus than rubber
- B. rubber is more elastic than steel
- C. steel deforms more readily than rubber
- D. Young's modulus equals stress divided by the original length
Example 3 · difficulty 2/5
A steel wire of length 2.0 m and cross-sectional area 3.14×10⁻⁶ m² hangs vertically from a rigid support. When a block of mass 20 kg is attached gently to its lower end, the elongation of the wire is closest to (Y = 2.0×10¹¹ N m⁻², g = 10 m s⁻²):
- A. 0.32 mm
- B. 0.64 mm
- C. 1.28 mm
- D. 6.4 mm
