To balance a see saw how do you figure how far from the fulcrum should you put the weight.

M1 * its distance from fulcrum = M2 times its distance from fulcrum IF the mass of the seesaw itself can be ignored.

To balance a see-saw, you need to consider the weight and distance from the fulcrum of each object on either side. Here's a step-by-step guide on how to figure out where to place the weight:

1. Determine the weights: Assign a value to the weight of each object or person on the see-saw. Let's say object A weighs 50 pounds and object B weighs 70 pounds.

2. Identify the fulcrum: The fulcrum is the pivot point or the center of the seesaw.

3. Calculate the moment: The moment of each object is the weight multiplied by its distance from the fulcrum. The moment is a measure of the turning effect caused by the weight.

Moment of object A = Weight of object A x Distance of object A from the fulcrum
Moment of object B = Weight of object B x Distance of object B from the fulcrum

4. Establish the condition for balance: For a see-saw to be balanced, the total moment on one side should be equal to the total moment on the other side.

Total moment on side A = Total moment on side B

5. Set up an equation: Using the moments and distances, you can set up an equation to solve for the distance at which the weight should be placed.

(Weight of object A) x (Distance of object A from the fulcrum) = (Weight of object B) x (Distance of object B from the fulcrum)

6. Solve for the unknown distance: Rearrange the equation and solve for the unknown distance.

Distance of object B from the fulcrum = [(Weight of object A) x (Distance of object A from the fulcrum)] / (Weight of object B)

Substitute the given values and calculate the distance.

By following these steps, you can determine the correct distance from the fulcrum for the weight to balance the see-saw.

To balance a seesaw, you need to consider the weight and distance of objects on both sides of the fulcrum. The moment or torque of an object is the product of its weight and its distance from the fulcrum. We can use this principle to figure out how far from the fulcrum you should put the weight to achieve balance.

Here's a step-by-step explanation:

1. Determine the weight of the objects on each side: Let's say you have a weight of W1 on one side and a weight of W2 on the other side of the seesaw.

2. Decide the distance of the fulcrum: The fulcrum is the point at which the seesaw rotates. You need to choose a location for it.

3. Calculate the moment or torque on each side: The moment is calculated by multiplying the weight by the distance from the fulcrum. On one side, the moment (M1) is equal to W1 multiplied by the distance from the fulcrum. On the other side, the moment (M2) is equal to W2 multiplied by the distance from the fulcrum.

4. Check for balance: To balance the seesaw, M1 should be equal to M2. This can be expressed as M1 = M2.

M1 = W1 * D1, where D1 is the distance of W1 from the fulcrum.
M2 = W2 * D2, where D2 is the distance of W2 from the fulcrum.

Therefore, to balance the seesaw, W1 * D1 = W2 * D2.

5. Rearrange the equation: If you know the weights on each side (W1 and W2), you can rearrange the equation to find the distance from the fulcrum:

D2 = (W1 * D1) / W2

This equation tells you how far from the fulcrum you should put the weight on one side to balance the seesaw based on the weight and placement of the object on the other side.

Remember, it's important to consider weight and distance when balancing a seesaw. Adjusting the position of the weights on either side of the fulcrum will help you achieve balance.
