There is a ladder leaning to the wall in your room. The ladder looks like it is about to slide down and fall. What would you do? How would you fix it? You will make it stand more vertical, right? Well...why? Draw a diagram, show all the forces that are present, and find the net torque. Do you see why a more vertical position is more stable?
