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,...

2. A h elical compression spring is made of 302 stainless steel wire. The outside coil diameter of the spring 1S 33.2 mm. The wire diameter is 2.8 mm. The ends are plain and ground, and there are total of 8.5 turns. Determine the deflection of the spring when it is subjected to a compression force of 10 N. In this condition, will the stress generated in the spring be beyond the maximum allowable torsional stress? (30 points)

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. Corner Springs Center Spring Mean Diameter, D 40 mm 25 mm Wire Diameter, d 5 mm 5 mm Active...

A cylindrical 2014-T6 aluminum alloy bar is subjected to compression-tension stress cycling along its axis, results of these tests are shown in Animated Figure 8.20. If the bar diameter is 10 mm, calculate the maximum allowable load amplitude (in N) to ensure that fatigue failure will not occur at 1.0 x10' cycles. Assume a factor of safety of 2.9, data in Animated Figure 8.20 were taken for reversed axial tesion-compression tests, and that S is stress amplitude. FE N [The...
