What is the vector loop equation around this 5 bar linkage?, all joints are rotary and the coordinates of joint (J1) is shown, please provide the closure equations in a way they can be broken down into two scalar components (x,y), use sin and cos for angles, please. ( This is part of the strider linkage mechanism, it is the bottom left leg)
