Suppose you grab the middle of the spring and hold it perfectly still. Now un-stretch the left half of the spring (the part to the left of where you grabbed it). Nothing about the right half of the spring has changed, so the force applied to the right half of the spring must ( F2 ) be the same F1 we found earlier.

What is the formula for spring stiffness?
The constant spring stiffness formula is the force applied to the spring equal to the stiffness times the distance it moved. F=kx. Depending on where your axis are, it could be negative.
What is spring-stiffness?
Spring stiffness is a property that relates load to deflection. Let k = stiffness and P = load and x = deflection, then P = kx The stiffer the spring, k, the smaller the deflection under a constant load. k can be measured for springs and otherdevices, such as beams, with simple load deflection devices or machines that measure deflection as function of laod
What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
What is Stiffness of a helical spring?
a helical spring has N turns of coil of diameter D, and a second spring made of same material and of same wire diameter has N/2 turns of coil of diameter 2D. if stiffness of first spring is k, then stiffness of second spring is
How eliminate surge phenomenon in spring?
Surge in springs is avoided by the following methods. (i) The spring is designed in such a way that the natural frequency of the spring is 15 to 20 times the frequency of excitation of the external force. This prevents the resonance condition to occur. (ii) The spring is provided with friction dampers on central coils. This prevents propagation of surge wave. (iii) A spring made of stranded wire reduces hte surge.
If the length of a spring is halved the spring constant becomes?

If length of spring is halved spring constant becomes?
2
Length of the spring is halved then the spring constant becomes?
Double
If the length of the spring is halved what happens to the spring constant?
Nothing; it remains the same as before.
How does length of spring coil affect the force constant?
The force constant is unaffected; It is a constant.
If the length of a spring is halved the stiffness becomes?
If spring is cut into two parts, each spring will have it's stiffness doubled. For n parts, stiffness of each part will be nk
What happens to pressure when the temperature and volume is halved?
if kelvin temp is halved, the volume is halved if pressure is constant.
A 1.2 kg of cheese is placed on a vertical spring of negligible mass and a force constant of 1800 N over m What is the length of compression of the spring?
Length of compression of the spring = (1.2*9.8)/1800
What happens to the resistance when length is doubled n area is quadrupled?
It is halved.It is halved.It is halved.It is halved.
Does the length of a string have any effect on the reading of the spring scale?
No, the length doesn't affect the reading because the mass is constant and therefore, the weight is constant. The string's weight is so small that it can be neglected.
Why current becomes halved when load is halved in transformer?
Load halved means the power is halved.Voltage being (assumed) constant, the current is halved. P (Load in Watts)= V x I Hence P/2= V x I/2
What happens to the area of a rectangle if the length decreases by one-half?
The area is directly proportional to both the length andwidth of a rectangle. Thus if one is halved then the area is also halved.
