1."In this exercise, you will be finding the resultant torque from the cross product of a lever arm with a force vector. The lever arm vector is A=2.0i+3.0j. The force vector is B=3.0i-4.0j. Find A x B B x A and 2A x 3B 2.My teacher has been sick the past few days so hasnt taught us anything about torque yet, but the homework is still due. I'm not sure where to start because every formula i've read about how to do these says to include sinθ, but an angle was not given. 3. is it just: 6i-12j+1k -6i+12j-1k and 36i-72j+6k? Someone please help me understand how these are done.
