There could be a few reasons for this. First, check to make sure you are summing all the moments correctly, including the signs. Also, check if all the forces and distances are accounted for in your calculations. If everything seems to be correct, there may be a mistake in your diagram or in the given information.
No, all forces and distances must be accounted for when summing moments. Neglecting any of them will result in an incorrect sum.
This could be due to differences in the chosen point of rotation, or a mistake in one of your calculations. Double check your work and compare it with your colleague's to identify any discrepancies.
Yes, you can choose any point as the point of rotation when summing moments. However, it is usually easier to choose a point where some of the forces are acting, as this will result in fewer calculations.
If all the forces and distances are accounted for and the sum of moments equals zero, then your sum of moments is correct. You can also check by comparing your calculated values to the given values, if available.
