    What is the Initial Torque of a Rod with an Acting Force?

    Homework Statement A rod is initially along the y-axis and has length ℓ. A force F =ˆı F1 +ˆj F2 + ˆk F3 acts at the upper end of the rod. What is the initial torque ~τ about the lower end of the rod? 1. Zero 2. ˆıF3 ℓ 3. −(ˆı F3 +ˆj F2 + ˆk F1) ℓ 4. (ˆıF3 − ˆk F1) ℓ 5. (ˆıF1 +ˆj F2...
