Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

A helical compression spring is made with oil-tempered wire of diameter 0.2", mean coil diameter of 2", 12 total coils, 5" free length, and squared ends. (a) Find the solid length. (b) Find the force required to compress the spring to closure? (c) Find the factor of safety against yield when compressed to the solid length. (Hint: Uses Say= 0.5 Sut for shear strength.)
Design a helical compression spring for a maximum load of 1000 N for a deflection of 25 mm using the value of spring index as 5. The operating load is considered as average load service. Choose a suitable material from table (23.1) for your design. If the same helical compression spring that was designed in Q1, is subjected to a load which vary from 200 N to 600 N. Based on the new condition, will the spring endure the new load? Consider that the allowable shear stress in table (23.1) is the yield stress and the endurance shear stress is 0.8 to 0.9 of the yield in shear. mechanical desgin pls solve fast
