# How Can I Find Moments for My Homework?

• suspenc3
In summary, the conversation discusses how to accurately calculate the distances from the moment using the equation M_A = Fd. The individual has tried summing all forces and their directions, as well as summing all forces from point G (center of gravity), but has not yet found the exact answer. The importance of including the force acting through the center of gravity in the calculations is also mentioned, as it affects the reaction force at the right end. It is suggested to sum moments about the right end to avoid the need for this force in the calculations.

## Homework Equations

$$M_A = Fd$$

## The Attempt at a Solution

I using the above equation..just summing all of the forces and their directions but I keep getting the wrong answer(distances from the moment). I also tried summing all the forces from point G (Center of gravity). This gave me a close answer but not exact. How should I go about doing this?

you said your answer is close to the answer given right?well i was wondering maybe you left out the 0.5m in the claculation?

Does the force acting through the Center of gravity come into play?

Yes. It is easiest to sum moments about the right end, and set them equal to 0. If you sum moments about G, you still need to know the force through G in order to calculate the reaction force at the right end, which will then contribute to the moment about G. When you sum moments about the right end, you don't need to know that force to do so, since it doesn't contribute to the torque.

## 1. What are moments in scientific research?

Moments in scientific research refer to significant events or breakthroughs that have a significant impact on the field. These can include new discoveries, advancements in technology, or paradigm shifts in understanding.

## 2. Why is having trouble finding moments a common issue in scientific research?

Finding moments in scientific research can be challenging because it requires a combination of creativity, critical thinking, and patience. Additionally, the scientific community is constantly evolving, making it difficult to keep up with all the latest developments.

## 3. How can I improve my ability to find moments in scientific research?

One way to improve your ability to find moments in scientific research is to stay updated on the latest advancements in your field by reading journals, attending conferences, and networking with other researchers. Additionally, keeping an open mind and approaching problems from different perspectives can also help spark new ideas.

## 4. What can I do if I have trouble finding moments in my own research?

If you are having trouble finding moments in your own research, it may be helpful to seek input from colleagues or mentors. They may offer fresh perspectives or suggest new approaches to your work. Additionally, taking breaks and stepping away from your research can also help clear your mind and potentially lead to new insights.

## 5. How can moments in scientific research impact society?

Moments in scientific research can have a significant impact on society by driving technological advancements, improving our understanding of the world, and addressing pressing issues such as climate change and disease. They can also inspire future generations to pursue careers in science and contribute to the progress of society.
