Homework Statement I have this arrow head geometry question (Please see diagram). I know L1, L2 and L3, angle B and the constant k (notice how the corner angle is equal to k * t2). I don't know t1 and t2. I'm pretty sure I have enough constraints, I'm just having trouble finding the right...

I have a three link revolute manipulator at the origin. I know all the link lengths. The joint angle for the third link is coupled to the second such that Theta3 = k*Theta2. I want to determine the joint angles (thetas) of the manipulator given that the third link should lie on a line an angle...

I have a 3D shape described by a triangulation map i.e. a map between the vertices to the faces of the shape which are all triangles. I then sliced the shape by a plane and computed the intersections of the plane and the triangle faces. Each triangle face that intersects the plane, will have...

Sorry, I realize I wasn't clear. Thankfully, Jerich made sense of it: Wow this was really amazing. I see how differently you set up the equations. I was thinking of doing something like Tspring = Tforce Tspring = [k1+k2 -k2 0 0; -k2 k2+k3 -k3 0; 0 -k3 k3+k4 -k4; 0 0 -k4 k4] x [theta1dot...

i want to make sure that the moment felt by the first link due to the force is not a big lever arm from the first joint to the location of the force on the third. (and in this way, the moment felt by the second joint would also be a longer lever arm then currently in the fbd). I'm thinking...

I went back and did some fbd's. the top part of the image i attached is my problem, the second are my fbd's which now seem to indicate that the moment felt by the first link due to the force is only a short lever arm rather than a long one. is that correct?

if i have a three link massless manipulator (each with length l1 l2 l3) that has rotational springs at each joint, k1 k2 k3, and I apply a force on the third link, what will be the joint angles at equilibrium? do I find the lever arm to each joint and multiply that by the force to find the...
