Frictional Block Free Body Diagram with corrected moments position for Normal Contact Force

Frictional Block Free Body Diagram with corrected moments position for Normal Contact Force, an Advanced Level Physics Case.

as suggested by workshop participant from JJC, moments are calculated and reflected in simulation!

angle = 0, block does not rotate
http://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/02-dynamics/42-friction

angle = 45, block does not rotate, normal contact force shifts to the extreme lower end of the block, just in position to not rotate clockwise.http://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/02-dynamics/42-friction

angle > 45, block  rotates (but not simulated), normal contact force shifts beyond the extreme lower end of the block, in real life, block will rotate clockwise.http://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/02-dynamics/42-friction
