Three springs of spring constant(adsbygoogle = window.adsbygoogle || []).push({}); kare connected to a body of massmand rigid supports, so that the angles are

A 90 degrees between two and 135 degrees between each of these two and the third.

B 120 degrees between any 2 adjacent ones.

Find time period of vibration.

I worked out a method to solve this question. I added 2 of the spring constants vectorially, first dividing each by the cos of half of the angle between them (45 and 60 degrees) and the third simply as k to get a net spring constant. This gave a correct answer but I don't remember what logic I used and it may not have been correct. Could someone show me the correct solution?
