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