SUMMARY

The discussion centers on evaluating the extension value (x) of a spring under a load (w) of 6 N using the formula F = kx. Participants clarify the relationship between load and extension, noting a positive correlation where the spring extends approximately 27 mm per 0.1 N. The calculation for k, the spring constant, is derived from the equation k = F/x, where F is the applied force and x is the extension. The participants emphasize the importance of accurate measurements and understanding the experimental setup to derive meaningful results.

PREREQUISITES
  • Understanding of Hooke's Law and the formula F = kx
  • Basic knowledge of spring mechanics and elasticity
  • Familiarity with measuring displacement in physical experiments
  • Ability to perform calculations involving force, mass, and acceleration
NEXT STEPS
  • Learn how to calculate the spring constant (k) using experimental data
  • Explore the relationship between force and extension in different types of springs
  • Investigate the effects of varying loads on spring behavior
  • Study the principles of elasticity and material deformation
USEFUL FOR

Students in physics, engineers working with mechanical systems, and anyone conducting experiments involving springs and force measurements will benefit from this discussion.

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.
 
  • #15
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.

plese i can't understand help me

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.
