in this diagram i made:
[PLAIN]http://img201.imageshack.us/img201/1856/physicsqa.png
left: simple application of linear force at center of mass
middle: application of linear force offset from center of mass gives rise to torque around center of mass
right: how to explain the forces and torques here?
most books just say that the contact point with the fixed object becomes the fulcrum
but i want to understand how that happens
i have drawn about 20 diagrams - and none of them make sense
the closest to an explanation i have got:
as the torque is a force applied to all points in the mass
the contact force is 1/2 the torque
an equal and opposite torque reaction somehow adds this 1/2 to the original ...
can anybody explain this?
