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...

2, A helical compression spring is to be designed to carry a variable load. The load varies from a minimum of F,=4 lbf to a maximum of F, = /8 lbf. The corresponding spring length varies from a maximum of L, 2.5 in to a minimum of L, =1 in. The outside diameter of the spring is Do = 0.638 in; the material is hard-drawn wiree of diameter d = 0.080 in. The free length of the spring is L...

Design a helical compression spring subjected to a varying axial force of 1000 N to 2000 N, is made of circular steel wire. Over this force range, the deflection of spring should be approximately 5 mm. Consider spring index = 5, for the spring that has square and ground ends. The spring is made of patented and cold drawn steel wire of grade 1 with A and m = 1753 and 0.182 respectively. The permissible shear stress for the spring...

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,...
