Homework Help: Physics

Posted by Kristi on Tuesday, August 16, 2011 at 1:32pm.

The drawing (which I will describe) shows a top view of a door that is free to rotate about an axis of rotation that is perpendicular to the screen. Find the net torque (magnitude and direction) produced by the forces F1 and F2 about the axis. Picture displays a yellow horizontal line (the door) whose axis is measured at 0.500m from the left side of the door. The larger portion of the door, on the right side of the axis, measures 1.10m. F1 points upward onto the very left edge of the door while F2 points at a diagonal, leaning to the left, but onto the very right edge of the door. This angle that it creates here, with a y-axis dotted line, is 30 degrees. F1 is 20 N while F2 is 35 N.
