$LDForces

Record identifier of LinkageData. It stores a list of forces that acting on the mechanism. Forces are stored as {{str1,vec},{str2,pointofAttack}} sublist
  • Forces are defined with two vectors. The first one specifies the magnitude and orientation of the force, while the second one specifies the point of attack.
  • str1 is the full name of the link,whose LLRF is the coordinate's frame, where the force vector (vec) is defined .
  • vec 3 dimensional vector defining the force vector.
  • str2 is the full name of the link,whose LLRF is the coordinate's frame, where the point of attack vector (pointofAttack) is defined.
  • pointofAttack 3 dimensional vector defining the point of attack of the force.
