Question
Problem 7: A weight W=2400lb is supported by a spring (or springs) as shown in figure below. A certain natural frequency of vibration of the weight is desired, and the spring rate necessary is found to be 1500lb/in. A junkyard has a group of identical steel springs available with the following specifications: Mean diameter = 3 in Spring index = 6 Number of active coils = 8 Modulus of elasticity in shear = 12x10 psi Modulus of elasticity in tension = 30x10 psi (a) How many springs should be used and how should the springs be arranged to have the spring rate as close to the desired value as possible? (b) Assuming that each spring may be modified by cutting off as many turns as necessary and refinishing the end of each spring, how many active coils must be removed from each spring to give the desired spring rate of 1500lb/in? (c) What is the maximum stress in each spring for (a) and (b) above? T Spring or Springs
