SUMMARY

The discussion centers on solving a statics problem involving forces and moments, where the calculated distance x is determined to be 5/2 m. The participant confirms their calculations, which include the equations FR = -F1 - 3F1 = -4F1 and Mo = -F1(1) - 3F1(3) = -10F1, leading to the conclusion that x = -10/-4 = 5/2. Despite the answer not being listed in the textbook, it is validated by another participant who agrees that the calculation is correct.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Familiarity with force and moment calculations
  • Knowledge of algebraic manipulation of equations

Homework Equations

The Attempt at a Solution


I am getting 5/2 m as the answer.
(not a choice)

FR = -F1 -3F1 = -4F1
Mo = -F1(1) - 3F1(3) = -10F1
Mo = FRx
x = -10/-4 = 5/2

Your answer of 5/2 m looks correct to me.
 
Once again the correct answer does not appear in the textbook. Be not discouraged. It happens all the time. Your answer appears to be correct.
