Question

We have a rod that can rotate about a central axis. Two rockets are rigidly fixed to the rod that will give thrust vectors represented by arrows below. If weight is toward the bottom of the page, write the sum of torques equation for the rod. we know that there is a force 2 and in the direction above and we know only that F2 is twice the magnitude of F1 but we don’t know where F2 is exactly (assume that for now we know only that it is on the rod and to the right of the rotation axis but we don’t know the length of r2). If θ = 40.0 degrees and Φ = 60.0 degrees find r2 in terms of r1 if the bar

Answer 1

drawing?

Answer 2

here is the pic

Answer 3

If θ = 40.0 degrees and Φ = 60.0 degrees find r2 in terms of r1 if the bar ....... bit missing at end
