What style of barricade on your door do you think is best?

  1. Aug 7, 2008 #1
    The yellow is the 2 possible places to bolt (with no nuts attached for quick removal) a 2 by 4 or some metal tubing to the floor. Would it be stronger to put it on an angle or straight on.

    - or \ ?

    Red is the interior walls of the house and black is the door. This is an aerial view. Grey is the natural path of the door.

    So would the yellow or green(lime) be better design.
    With the lime one you would have it flush against the door and the interior wall with then ends cut pointy to fit.

    Would this be better than putting one on your door like you would see in rush hour when chris tucker meets his cousins at the poool hall?

    The green piece would be cut at an angle to fit flush.

    Yellow. Normal force applied at an angle to the closed door to yield maximum torque.

    But green probably takes up less room.
