- Hello! I was doing this question from a textbook and I am Unsure why my answer is slightly different to that of the textbook
- Relevant Equations
- M = Fd
SF1 + SF2 =SFT
The problem states explicitly that the forces are assumed to act where the bridge meets the supports. I’d go with the rounding option.TSny said:Also, the support forces at each end might be considered as acting in the middle of the 1-meter width rather than at the edge (dashed):
Yes, I overlooked the comment about the location of the forces. Thanks.Orodruin said:The problem states explicitly that the forces are assumed to act where the bridge meets the supports. I’d go with the rounding option.
A moments question typically involves finding the sum of moments or torques acting on a system. It is a common type of problem in physics and engineering that requires understanding of rotational motion.
When solving a moments question, you should first identify all the forces acting on the system and their respective distances from a reference point. Then, calculate the torque produced by each force and sum them up to find the total moment.
Common mistakes in moments questions include forgetting to account for all the forces acting on the system, using incorrect distances, and not considering the direction of the torque. It is important to be careful with your calculations and double-check your work.
To improve your skills in solving moments questions, practice solving a variety of problems and familiarize yourself with different scenarios. It is also helpful to understand the underlying concepts of moments and torques in order to approach problems more effectively.
If you are unsure where you went wrong in solving a moments question, you can seek help from your teacher, classmates, or online resources such as textbooks, tutorials, and forums. Working through problems collaboratively can also be beneficial in gaining a better understanding of moments.
