Yes, you are right, in respect to the horizontal, of course they shorten, if the mass is increased without any spring adjustment. But what I need to do is maintain the mass at its respective attitude. Therefore the arms remain static, the spring is then adjusted to compensate for the increased...
Thanks Simon. At the point of the mass, the resultant spring force is indeed acting directly upward. The parallelogram is of a fixed length of arm. The left had side is tethered, however the right hand side can only move in a vertical direction upwards or downwards, ok, it will move slightly...
Hi Simon,
When the spring is more towards the horizontal, and both adjusters are slackened right off, it's spring length is shorter than when both adjusters are at a maximum, when the spring is at say 22 deg to the horizontal. This puts the spring under more tension as it is longer surely? This...
I am building a shock damper for various weights which will be added at Mass D below. What I need to calculate is by how much would I need to turn my adjusters thus changing the angle of the spring, which in this case is 14.9 Kg rated, to allow for different weights to remain at a level...
