In the arrangement as shown in the figure, the stepped steel bar ABC is loaded by a load P. The material has Young’s modulus E = 200 GPa and the two portions AB and BC have area of cross section 1cm2 and 2cm2 respectively. The magnitude of load P required to fill up the gap of 0.75mm is
  • a)
    10 kN
  • b)
    15 kN
  • c)
    20 kN
  • d)
    25 kN
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
In the arrangement as shown in the figure, the stepped steel bar ABC ...
E = 200 GPa = 200 x 103 MPa
AAB = 1 cm2 = 100 mm2
ABC = 2 cm2 = 200 mm2
Gap(δ) = 0.75 mm
There will be no deformation in BC so,
δAB = δ
P = 75 x 200 = 15 x 103N = 15 kN
