Webb18 okt. 2024 · θ = 180° (or π radians) - This is a situation where the force vector points directly into r. Again, shoving toward the axis of rotation isn't going to cause any rotation either and, once again, the mathematics supports this intuition. Since sin (180°) = 0, the value of the torque is once again τ = 0. θ = 90° (or π /2 radians) - Here ...
