Question
Download Solution PDFTwo closely coiled helical springs A and B are equal in all respects but for the number of turns, with A having just half the number of turns of that of B. What is the ratio of deflections in terms of spring A to spring B?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
For closed coil helical spring,
Where, R = radius of coil of spring, n = number of turns, G = modulus of elasticity and r = radius of wire of coils
From the above formula, it is clear that the deflection is directly proportional to the number of turns keeping all other parameters same.
Calculation:
Given,
Number of turns in spring A = ½ time the number of turns in B
