1) [60 pts] Helical Compression Spring A helical compression spring is wound using music wire of diameter, d, 2.64 mm. The spring has an outside diameter, OD, of 33 mm with plain ground ends and 14 coils. a) Estimate the spring rate. The spring rate is N/mm. b) What is the force needed to compress this spring to closure assuming that the spring will reach its shear strength at its solid length? The force needed to compress this spring to...

Design a compression spring with an outside diameter of 11.00 inches from round type 302 stainless-steel wire to operate a plate dispenser in a cafeteria. When fully loaded, the spring is to be compressed 45 inches below the stop under a load of 80 lb, and when empty the spring should exert a force of 0.50 lb against the stop. The ends of the spring are closed. Specify the wire diameter, the number of active turns, the total number of...

A stock helical-coil compression spring has a total of 14 coils, both ends squared and ground, a free length of 1.25 in, and an outside coil diameter of 7/16 (0.438) in giving the number of active coils, Ng=12. The material is hard- drawn wire 0.042-inch in diameter and S=259,000 psi. The operating forces are Fmin=1.5 lb and Fmax=3.5 lb.

2. A helical compression spring is to be designed as shown in Fig Q2. The spring is required to exert a force of Po-102 N when compressed to a length of lo=44 mm. When its length is 1=76 mm, it must exert a force of P=22 N. The spring will be cycled rapidly, with severe service required. Use ASTM A401 steel wire. The factor of safety, η, need to be larger than 1.5. Starting with a spring index of 9,...

1- A helical compression spring is to be made of oil-tempered wire of 4-mm diameter with a spring index of C = 10. The spring is to operate inside a hole, so buckling is not a problem and the ends can be left plain. The free length of the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm. (a) Determine the spring rate. (b) Determine the minimum hole diameter for the spring to...
