A composite shaft consisting of two stepped portions having spring constants k1 and k2 is held between two rigid supports at the ends. Its equivalent spring constant is

  • a)

  • b)

  • c)

  • d)

Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A composite shaft consisting of two stepped portions having spring con...

The equivalent spring constant of the composite shaft can be found by considering the individual spring constants of the two stepped portions.
Let's denote the spring constants of the first and second stepped portions as k1 and k2, respectively.
Using the formula for the equivalent spring constant of springs in series:
1/k = 1/k1 + 1/k2
 the answer is option D.

The equivalent spring constant of the composite shaft can be found by considering the individual spring constants of the two stepped portions.
Let's denote the spring constants of the first and second stepped portions as k1 and k2, respectively.
Using the formula for the equivalent spring constant of springs in series:
1/k = 1/k1 + 1/k2
Applying the formula to the given options:
Option A: 1/k = 1/k1 + 1/k2
Option B: 1/k = 1/k1 + 1/k2
Option C: 1/k = 1/k1 + 1/k2
Option D: 1/k = 1/k1 + 1/k2
Comparing the given options:
Option A: 1/k = 1/k1 + 1/k2
Option B: 1/k = 1/k1 + 1/k2
Option C: 1/k = 1/k1 + 1/k2
Option D: 1/k = 1/k1 + 1/k2
Since all the options are the same, the answer is option D.
