A spring with a spring rate of 75 lb/in has a working deflection of 1 in. It provides a minimum of 150 lb at installation. The spring is formed from 0.25 in diameter unpeened music wire. The coil has squared and ground ends, and it fits in a 2.1 in diameter hole with 0.1 in clearance.

Assuming a 15% clash allowance, find:

a) Safety factor for infinite life in fatigue

b) Shut height

c) Safety factor at shut height

d) Total number of coils

e) Free length

A 128-lb weight is attached to a spring having a spring constant of 64 lb/ft. The weight is started in motion with no initial velocity by displacing it 6 in below the equilibrium position and by simultaneously applying an external force F(t) = 8sin(4t). a. Assuming no air resistance, find the equation of motion. b. What is the long term behavior of the motion? Please use differential equations to solve this

A mass is connected by means of a spring to an inelastic support. The static deflection due to the weight of the mass is 60 mm. The support is oscillated with simple harmonic motion at 3Hz and amplitude 10.0mm. Determine the amplitude of vibration of the mass and phase angle if the damping is negligible. The mass is now damped in an oil bath which exerts a resistance proportional to velocity, and the spring anchorage is oscillated as before. It...
