Reactions calculation
R1 + R2 + R3 = 40
0.625R1 + 0.275R2 = 9
0.275R3 - 0.35R1 = 2
0.625R3 + 0.35R2 = 16
0.175R2 + 0.45R3 - 0.175R1 = 9
Please calculate R1, R2, R3 and tell me i m very thankful to you.

But sir we are here at upper position because we have more equations then no. of unknowns so what is the reason that corresponding reactions are indeterminate.bioramaniThere seems to be a redundancy in this. Only three independent equations are required for three variables.
There are four here.

In this problem the data given has a little error and so makes solving not possible you seeAmmar AzizBut sir we are here at upper position because we have more equations then no. of unknowns so what is the reason that corresponding reactions are indeterminate.

error of what type. i assure you that the data is correct. but if you have objection then what is the criteria on which we decide that whether the reactions are indeterminate or not.jeffrey samuelIn this problem the data given has a little error and so makes solving not possible you see

What are these reactions that you are referring to? Reaction to a force? Are these experimental equations? If these are mechanical forces and if some non linear thing like thixotropic substances are involved forces can be indeterminate.Ammar Azizerror of what type. i assure you that the data is correct. but if you have objection then what is the criteria on which we decide that whether the reactions are indeterminate or not.

actually these equations are derived from the analysis of a beam hanging horizontally with three springs. at the same time we apply two loads on two loading hangers attached with the above mentioned beam. these equations are derived by considering the equilibrium condition and applying the "sum of moments around a particular point due to all forces is zero" principle. actually the reactions which i mention in my post are the reaction forces to applied loads. and it is the springs which react to the applied load by generating upward forces in beam. now i think situation is clear.bioramaniWhat are these reactions that you are referring to?
