1. The problem statement, all variables and given/known data A uniform door weighs 53.0 N and is 0.9 m wide and 2.5 m high. What is the magnitude of the torque due to the door's own weight about a horizontal axis perpendicular to the door and passing through a corner? 2. Relevant equations torque is equal to the perpendicular component of the force with the shortest distance between the roation axis and the point of application of the force and τ=r(Fsinθ) 3. The attempt at a solution 530*0.9*2.5*(sin90) i really don't know where to begin, my teacher hasn't taught this yet, even though the webassign is due tomorrow. am i using the wrong formulas?
