Compression springs are the most common spring configuration that product manufacturer's turn to when enhanced product functionality is required. You are required to design a compression spring that is made of oil-tempered wire of 4-mm diameter with a spring index of C=10. The spring will operate inside a pipe, so buckling is not a problem and select the ends to be plain. The free length of the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm. a) Calculate the spring rate and the solid length. b) Calculate the total number of coils needed. c) Calculate the minimum pipe diameter for the spring to operate in. d) Calculate a static factor of safety based on the yielding of the spring if it is compressed to its solid length.
Problem E8.2. Multiple constraints: a cheap column that must not buckle or crush (pg. 314). The best choice of material for a light strong column depends on its aspect ratio: the ratio of its height H to its diameter D. This is because short, fat columns fail by crushing; tall slender columns buckle instead. Derive two performance equations for the material cost of a column of solid circular section and specified height H, designed to support a load F large compared to its selfload, the first using the constraints that the column must not crush, the second that it must not buckle. The table summarizes the needs. Function Constraints Objective Free variables Column Must not fail by compressive crushing Must not buckle Height H and compressive load F specified. .

A helical compression spring is required to design, which be subjected to a maximum force of 1250 N. The deflection of the spring corresponding to the maximum force should be approximately 30 mm. The spring index can be taken as 6. The spring is made of patented and cold-drawn steel wire. The ultimate tensile strength and modulus of rigidity of the spring material are 1090 and 81370 N/mm² respectively. The permissible shear stress for the spring wire should be taken as 50% of the ultimate tensile strength. Design the spring and calculate: i) Wire diameter, ii) Mean coil diameter, iii) Number of active coils, iv) Total number of coils, v) Free length of spring, vi) Pitch of coil.
A composite spring has two close coiled helical springs connected in parallel and compressed between two parallel plates by a load of 1000 N. Each spring has 10 coils and is of the same initial length. The springs have a wire diameter of 10 mm, and the radii of coils are 50 and 75 mm. If the smaller spring is placed inside the larger one such that both the springs are compressed by the same amount, calculate: a) The total deflection, and b) The maximum stress in each spring. Take G = 40 GPa for both the springs
