To determine the force applied that causes an extension of 5mm, you need to know the spring constant of the object. The spring constant represents the stiffness of the spring and is usually denoted by the symbol "k".
Once you have the spring constant, you can use Hooke's Law, which states that the force applied to a spring is directly proportional to the extension or compression of the spring. Mathematically, it can be expressed as:
F = k * x
where F is the force applied, k is the spring constant, and x is the extension or compression of the spring.
To find the force applied, you need to rearrange the equation:
F = k * x
Plugging in the given values:
F = k * 5mm
Now, if you have the spring constant value in units of N/m (newtons per meter), the force applied will be in newtons. If the spring constant is in different units, like N/cm or N/mm, you will need to convert the units accordingly.
To determine the force applied that causes an extension of 5mm, you need to know the material's stiffness or spring constant. The formula to calculate this force is given by Hooke's Law:
Force = Spring Constant * Extension
So, if you know the spring constant of the material, you can directly calculate the force applied by multiplying the spring constant with the extension.
However, if the spring constant is not provided, you can determine it experimentally by using a device known as a force gauge or a spring balance. Follow these steps to measure the force applied:
1. Attach the material to be tested to the force gauge. Make sure that the gauge is set to zero before starting.
2. Apply an initial force to the material and record the corresponding extension. You can manually apply the force and measure the extension using a ruler or vernier calipers.
3. Repeat step 2 for different force values, maintaining a constant force increment, and recording the extension each time.
4. Plot a graph of force applied (x-axis) vs. extension (y-axis). This graph should show a linear relationship.
5. Calculate the slope of the graph, which represents the spring constant. The slope is given by the formula:
Spring Constant = (Change in Force) / (Change in Extension)
6. With the spring constant determined, you can compute the force applied for a given extension by rearranging Hooke's Law:
Force = Spring Constant * Extension
By plugging in the spring constant value you determined experimentally and the given extension of 5mm, you will be able to find the force applied that causes the extension.
