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.

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...
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,...

Problem 3. A plate is resting on four identical helical compression springs at its four corners. The plate is loaded centrally so that each of these springs undergoes same amount of deflection. For safety, a much harder spring is placed at the center of the plate. The free lengths of the softer springs are 20 mm more than the harder one.

The rigid beam ACE is subjected to the load P and suspended at points A, C, and E
The rigid beam ACE is subjected to the load P and suspended at points A, C, and E by three suspender bars AB, CD, and EF (see Figure 1). These three suspender bars are made of the same steel and have the same circular cross section with the same diameter of d=30 mm. The ultimate 2m stress of steel is σu=450 MPa and Young modulus is E=200 GPa. (a) Using a factor of safety FS=1.5, determine the All maximum allowable load...

Ordinary window shade rollers have long torsion springs that work on the same principle as the overhead garage door support of Problem 12.59. For a roller of 33-mm diameter, how many turns of 1.2-mm square steel wire with D = 19 mm would be required to give a shade pull force of 14 N with the spring wound up 14 turns? What would be the value of maximum bending stress in the spring? 33 mm dia. 33 mm dia. Cable...
