PhanthomJay said:I didn't see much of an attempt. Is the load in the center of the table? If no, forget about finding the reactions without a computer program or a copy of Roarke's 'Stress and Strain". If yes, the solution is relatively simple.
It appears that the outrigger supports are symmetrical about the axes of the plane, in which case you could represent the loading as equivalent forces and couples appied at the COG, and compute reaction forces at the 4 supports by looking at the components of the loading about each respective axis, computing the reactive forces accordingly by applying the equilibrium equations in each direction (noting due to symmetry that the loading is shared equally by the near and far supports), then add them up algebraically (a corner support may take the maximum load).aoide said:@phantom
thanks for your explanation, i think i start to get the idea..
anyway, how about picture in this link..

could it use symetrical?? COG for body and antenna in middle.. but the leg/support not in same plane (see picture from above)
do you have email?? i want to ask you some question, please send your email to g.ghunk.np@gmail.com
thanks again
In order to determine these forces, you will first need to draw a free body diagram of the object or system in question. Next, use the equations of static equilibrium (sum of forces in x, y, and z directions equal to 0 and sum of torques equal to 0) to set up a system of equations. Finally, solve for the unknown forces using algebra or other mathematical methods.
Determining these forces is important because it allows us to understand the stability of an object or system. It also helps us analyze and predict the behavior of structures under different loading conditions.
No, in order to accurately determine these forces in a 3D static equilibrium, you will need to use the equations of static equilibrium in all three dimensions. Using 2D equations will not give you the complete picture and may lead to incorrect results.
Yes, some common assumptions include the object being in a state of rest, having a constant and uniform density, and all external forces and torques acting at a single point.
Yes, this concept is commonly used in engineering and design to analyze and optimize the stability and strength of structures such as bridges, buildings, and machines. It is also used in physics and mechanics to study the behavior of objects under different forces and loads.
