Tipping Block.
PIRA: Unknown
A large wooden block is placed on a rough surface so that it will not slide. A force is applied with a spring balance, first parallel to the horizontal along the top edge and then perpendicular to a diagonal drawn to the tipping axis. The required force to move the block is less in this case.
