Statically inderterminate analysis
Statically inderterminate analysis
(OP)
I am trying to solve for forces in a wheelchair lifting device that mounts to the rear of vehicles. The only known force I have is the wheelchair weight. I am not looking for information on computer software, just some resources on solving by free body diagrams and hand calculations.






RE: Statically inderterminate analysis
Can you supply more information on how this device is fastened to the vechicle, if its just bolted on with say two
rows of fixings like a wall bracket then the calculations are not that difficult and I may be able to help you further.

So are you looking to calculate the forces in the four bar linkage? What does the linkage look like ie:- does it form
a scissor type mechanism? its difficult to help when we don't know what the configuration is other than a four bar mechanism.

Thanks

Do you have a text book on structural mechanics? That's the kind of reference you will need for hand analysis of this kind of problem.
