(OP)
HI,
I am trying to apply vector force(unit force) at one end of the simulated 4-barlink mechanism. I used Revolute+Revolute+Universal and Ball joints at each end.
Grubler count is shwoing 0 and the dof also zero (with driver on one of the revolute joints).
Now when I apply unit vector force, when I run the for excel map the simulation is giving a torque of 0.9psi where as the FBD free body diagram gives an end torque of 8.63psi.
Pl guide.
Thanks

You refer to the ground joint as the 'driver'; are you applying any force to this joint, or only the unit force at the end of link 1? Are you simulating a range of motion or just this one position?
