A helical compression spring with squared and ground ends has an outside diameter of 1.100 in, a wire diameter of 0.085 in, and a solid height of 0.563 in.Compute the ID, the mean diameter, the spring index, and the approximate number of coils.
Need only handwritten solution only (not typed one).
A helical compression spring is subjected to a maximum force, Fmax of 1250 N. The deflection of the spring corresponding to the maximum force should be approximately 30 mm. The spring index is 6. The allowable shear stress is 350 MPa and the modulus of rigidity is 81 370 N/mm². Design the helical spring by calculating the wire diameter, mean coil diameter, number of active coils and the total number of coils. State all assumptions and decisions in your design.
A helical compression spring is required to provide a minimum force of 150 lb at installation and have a working deflection of 1 in. The spring rate is 75 lb/in. The coil must fit in a 2.1-in-dia hole with 0.1 in total clearance. Use 0.25-in diameter unpeened music wire and squared/ground ends.

Required information A solid square rod is cantilevered at one end. The rod is 0.6 m long and supports a completely reversing transverse load at the other end of ±1.7 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 5 x 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end. What will the strength of the metal be at 5 x 104 cycles? The strength of the metal at 5 x 104 will be MPa.
A rod is hanging vertically, supports a load of 2000N. Neglecting the weight of the wire, determine the required diameter if the tensile stress is 140MPa.
A helical compression spring is needed to fit over a 0.5 in. diameter rod. To allow for some clearance, the inside diameter of the spring is to be 0.6 in. To ensure a reasonable spring size, assume a spring index of 10. The spring is to be used in a machine where it will be repeatedly compressed from a free length of 5 in. to its solid length of 2 in. and then released. The spring should have squared and ground ends and is to be made from a cold-drawn A227 wire. (a) Determine a suitable wire diameter. (b) Determine a suitable total number of coils. (c) Determine the spring rate. (d) Where is the maximum stress in the wire of the spring? (e) Determine the static factor of safety when compressed to its solid length. (f) If the spring is to be designed for infinite life, what will be the mean stress and alternating stress on the spring. (g) Calculate the weight of the spring.

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
