Hi Thanks everyone. Baluncore, jrmichler, Berkeman special thanks to all of you for sharing your valuable time on this design issue. These information shared by you all is a tremendous source of knowledge. I am going through them. It may take a while. I am sure with these i may solve the problem...

Thanks for your reply. I am extremely sorry for not sharing the complete data. I did put minimal data so that the problem can be expressed in a way most can understand. Yes from here i can understand that you as an expert will appreciate the technical information i have. I need to design a...

Hi Thanks for your crisp reply. If i take telescopic route, then how can i go about it. Solid length is not an issue. It is preferable but also dispensable. Could you please guide Thanks again. I surely will try to go through the guides you have mentioned

Thanks for your reply. Have already done that. I am not sure whether the result is right or not because it assumes a boundary condition, which is not the case here

Non Telescopic is in a sense, that the coils of spring should not merge or immerse completely into each other.they should rather sit on each other. So the solid length of such a spring will be sum of dia of all the coils. In a telescopic spring, to my knowledge, the coils of spring will immerse...

What is the method to design a Non - Telescopic, Non - Linear, conical compression spring from a Force - Deflection characteristics

Thanks for your reply I need to design a nonlinear extension spring. I've readied a graph based on my design criteria. Based on this graph, i want to design the extension spring. please provide more insight on design methodology Moreover i must use a single spring of small weight and...

Hi Could anybody guide me to a software that can be used to design a non linear spring from load deflection characteristics. need it for both extension and compression spring. thanks noor

thanks for your anwer suppose the force on steel due to magnet kept below it at a distance of 1 cm is 20 N. and if this steel is moved horizontally just to be outside its magnetic field, then the force required, to move it disregarding friction, should be atleast 20 N. But it is observed that...

Hi I'd put the problem differently. A permanent magnet of known dimension and magnetic field strength B is fixed. A steel plate of known dimension and thickness and permeability is placed at a distance d, such that the pole of the PM faces the flat surface of steel. The force acting due to PM...

hi, thanks for your reply. the link has to do with electromagnets and the problem is very different. i know the magnetic field strength B. the steel is fairly bigger than the permanent magnet. there are two cases here. case1. steel is stationary at a distance d from the pole of magnet. i know...

Low carbon steel. it has very good magnetic property. I want to analyse the force required to move a steel plate in magnetic field for a project.

Hi A steel plate with dimensions a * b and thickness t is moving in a magnetic field of stationary permanent magnet. the movement of steel plate is parallel to the magnet field. One pole of the magnet is perpendicular to the axis of steel movement. what force will be required to move this steel...

a pendulum of length 'L' having a mass 'M' attached as it's bob and it oscillates with a time period 'T'. what will be the force tangential to the pendulum 1. just above the point of suspension of the pendulum 2. at a distance 'r' below the point of suspension

can someone help with this calculation two semicircle magnets N-S of strength 'B' encircle a solenoid of length 'L' and move with a constant velocity 'V'. what will be the current 'I' that is induced in solenoid. also, what force will the magnet experience because of this current (Lenz's law)
