Design a Belleville spring to give a static force of approximately 2000 lb at a maximum deflection of 0.05 in with a nearly constant spring rate.

1.       Design a Belleville spring to give a static force of approximately 2000 lb at a maximum deflection of 0.05 in with a nearly constant spring rate.

2.       Design a Belleville spring to give a static force of 400 lb at 50% deflection-to-flat and 200 lb at flat.

3.       Design a helical compression spring for a static load of 60 lb at a deflection of 1.50 in with a safety factor of 2.0 to work in a 1.06-in-dia hole. Specify all parameters necessary to manufacture the spring.

4.       1Design a helical compression spring for a static load of 200 N at a deflection of 40 mm with a safety factor of 1.8 to work in a 25-mm hole. Specify all parameters necessary to manufacture the spring.
