How Do You Evaluate the Extension Value Under a 6N Load Using F = kx?

    Extension Value
AI Thread Summary
To evaluate the extension value (x) under a 6 N load using the formula F = kx, one must first determine the spring constant (k) from experimental data. Participants discussed measuring the spring's elongation at various weights, noting that both increasing and decreasing loads yielded similar extension values. The confusion arose around the purpose of the "Decreasing" column in the data table, as it seemed to contradict the expected behavior of the spring. Ultimately, the relationship between weight and extension is positive, and the correct approach involves using measured values to solve for k before calculating x for the 6 N load. Understanding the relationship and accurately applying the formula is crucial for solving the problem.

evaluate the value of extension ( x) which elongate under the action of load (w) of 6 N ? [Use your results obtained from rest 1 ]



please help me How i can solve this question because I don't understand it clearly

plese I want your help
 
any one here ??
 
What is the question? What do the three columns on the right mean? Why do you have the same values for Increasing and Decreasing?
 
beacuse when we mesure we got same value to Increasing and Decreasing
 
I can see that, but I have no idea what you're trying to do here. What do Increasing and Decreasing mean in your table?
 
this experiment of Speing balance

when we increasind ( Load ) the space we are got in decreasing is same .

we start by 0.1 N then 0.2 then >>>> to 0.5
 
where are you ?
 
OK, for the first row in your table, you have Load = .1 N. Did the spring length change (increase) by 29 mm? If the spring got longer, it can't have also gotten shorter, so I don't understand the purpose of the Decreasing column or the Average column.

Look Dear

Experience as follows :

First, we put Spring on the board and a paper under spring to measure the distances between each point from the beginning to the end point of extension for each weight

Then we increased laod to ( 0.2 n ) the measurement was between the starting point until end point of extension is 51 mm (( same steps for all load ))

Then we've decrease the weights ( Every time one ) from end ( 0.5 ) to (0,1 ) we got same measurements

then We calculated the average by calculat increases and decreases and divide by 2




For information, there is a Positive relationship between weight and extension
plese help me

Dr. Mark44 where are you ?

It looks to me like the spring will extend about 27 mm per .1 N, or about 2.7 cm per N. How much will the spring extend with a weight of 6.0 N?

Is this ok help me

k = mg/x

0..04/1 = 6 / X

x = 6.6X10^-6 cm

plese help me

Where did the equation above come from, particularly "0..04/1"?

No, this is way off.

x = w/k

but from where we got the value of k ?
 
  • #16
You have the force (mg - Newtons), and you have the displacement (\Delta x).
 
  • #17
x = w/k =
6/k from where we got the value of k ? here we try to find x
 
  • #18
The purpose of your experiment was to measure values of F (the weight) and x.

The formula is F = kx.
The table you made has measured values of F and x, so solve for k in the equation F = kx.
