A uniform slender bar AB with a mass of 20 kg and length of 3.6 m lean

1.	A uniform slender bar AB with a mass of 20 kg and length of 3.6 m leans on a wall as shown. It is attached to a weightless small roller at end A on a smooth horizontal surface. The coefficient kinetic friction between end B and the wall is 0.25. If the bar is released from rest in the position shown when θ is 30°. Then find,determine the normal force at A.determine the normal force at B.determine the frictional force between end B and the wall.
Answer» ANSWER: The NATURAL environment or natural world encompasses all living and non-living THINGS occurring naturally, MEANING in this case not artificial. The term is most OFTEN applied to the Earth or some parts of Earth.
