Question

Two closely coiled helical springs A and B are respects but for the number of turns, with A having just half the number of turns of that B. What is the ratio of deflections in terms of spring A to spring B?

• A. 1/8
• B. 1/4
• C. 1/2
• D. 2/1

Answer 1

The correct option is C 1/2

$\because \Delta =\frac{64P{R}^{3}n}{G{d}^4}$

$\therefore \Delta \propto n$

$\therefore \frac{{\Delta }_A}{{\Delta }_B}=\frac{n_A}{n_B}=\frac{1}{2}$
