A compression spring is to be made from ASTM A227 steel wire, with a wire diameter of 8.0 mm, and is to operate under severe service conditions. The spring is to have an inside diameter of 34 mm, with squared and ground ends. It is to apply a force of 3.6 kN when at a length of 100 mm, and a force of12 kN when at a length of 140 mm. The number of active coils for this spring must be: O9.13 O 19.27 11.42 685 O 18.27 4.13 13.70 O 4.57

Problem 3: Design a helical compression spring to be used to return a pneumatic cylinder to its original position after being actuated. At a length of 10.50 in, the spring must exert a force of 60 lb. At a length of 4.00 in, it must exert a force of 250 Ib. Severe service is expected. Use ASTM A231 steel wire.
For the same question, the Impeller hub will be pressed onto the taper shaft with the Nut. How much FORCE should the nut create for this? Also, if the nut loosens and falls off, calculate whether the connection will be DISCONNECTED by itself. (Do not take the values from the previous question, use the values given in this question!)

Q5/ In vehicle suspension design it is desirable to minimize the mass of all components. You have been asked to select a material and dimensions for a light spring to replace the steel leaf-spring of an existing truck suspension. The existing leaf-spring is a beam, shown schematically in the figure. The new spring must have the same length L and stiffness S as the existing one, and must deflect through a maximum safe displacement 8max without failure. The width b and thickness t are free variables. L Load F 6= 1 FL³ 48 EI 10₂L² 6 #E 1=bt³/12 8max = Derive a material index for the selection of a material for this application. Note that this is a problem with two free variables: b and t; and there are two constraints, one on safe deflection 8max and the other on stiffness S. Use the two constraints to fix free variables.
Please help with all thank you!!
