Find the stress in central spring and plate displacement
Two concentric springs, the central spring being 5 mm shorter than the outer spring, are to be loaded as shown. The outer spring consists of 40 turns of 15 mm diameter wire coiled on a mean diameter of 100 mm. The central spring, on the other hand, has 80 turns of 20 mm diameter wire coiled on a mean diameter of 80 mm. Use 83 GPa and 76 GPa for the shear modulus of the outer and the central springs, respectively.
If the load P = 2 kN, determine the stress in the central spring and the displacement of the plate.

Central spring gap
A rigid plate of negligible mass rests on a spring system consisting of five vertical springs, four identical outer
springs in a square formation and another spring at their center. The central spring is 5 mm shorter than
the outer springs.Each of the outer springs consists of 25 turns of 20 mm wire on a mean diameter of 40 mm.
The central spring has 30 turns of 15-mm wire on a mean diameter of 35 mm.A load P = 40...
Compute for maximum load P for concentric springs
A load P is supported by two concentric steel springs as shown. Spring 1 consists of 30 turns of 15 mm diameter
wire on a mean diameter of 80 mm. Spring 2 has 25 turns of 20 mm diameter wire on a mean diameter
of 40 mm. Compute the maximum load that will not exceed a shearing stress of 140 MPa in either spring. Use G =
76 GPa.Compute for the maximum load P in kN.
