Homework Statement
2. Two helical springs of the same initial length are made from the same circular section wire and have the same number of coils. They are assembled co-axially and are compressed between two parallel plates by a force of 450 N. The mean coil diameters of the outer and inner springs are 100 mm and 75 mm respectively. Determine the load in each spring.
(Answer: 316 N, 134 N)
Homework Equations
F = (Τ x Pi x d^3) / (8 x D) ?
3. Own working
I tried using the figures in the above equation to calculate values for the Shear Stress T but wasn't sure how to separate the loads into a part for each spring.
Question as above, answers as well, but I can't figure out how to calculate them as I don't have the correct formula I presume.
Any help would be much appreciated, exam tomorrow looms. :(
