The lecture Torque and Equilibrium by Jared Rovny is from the course Equilibrium.
In the equation for torque, τ = rF sin(θ), what does r stand for?
When will the torque applied to be maximized for a given distance r and force magnitude F?
If the distance between the center of rotation and the applied force is 2 meters, and the angle between the force and the distance is 30 degrees, what is the length of the lever arm?
Why are doorknobs usually placed far away from the pivot point (center of rotation) of the door?
