*PLEASE DO PARTS E-H AND I IF YOU COULD!*

1. Evaluate a music wire spring with plain ends where the wire diameter is 0.100” and the outer diameter is 0.600”. The desired spring rate is 100 lbf/in and the free length is 2.4”. Let the load safety factor be 1.00.

a) What is the spring index, C?

b) What is the total number of coils, Nt?

c) What is solid length, Ls?

d) What is the maximum suggested load?

e) What is the maximum suggested deflection?

f) What is the force to close to solid, Fs?

g) What is the critical length?

h) What is the critical frequency?

i) What is the factor of safety, solid, ns?

A helical spring is to provide a minimum force of 600 N at installation and have a working deflection of 25 mm. The spring rate is 13 N/mm. The coil must fit in a 55 mm diameter hole with at least 2.5 mm clearance. Use a 6.5 mm diameter unpeened music wire with squared and ground ends. Using 15% clash allowance, find:- i. spring constant ii. free length of the spring. iii. the ‘solid’ length of the spring iv. Draw...
