A beam at 30° inclination rest between a wall and a floor. A hinged support with based at the floor is placed at point A while a roller support with vertical base is at point B. The beam is 6 m long and supports a 4.5 KN load L/4 meters from point B which is perpendicular to the beam.

a. What is the magnitude of the reaction (KN) at point B?
b. What is the normal force (KN) at midspan if the cutting plane is perpendicular to the beam and assumed in INWARD direction?
c. What is the shear force (KN) at midspan if the cutting plane is perpendicular to the beam and assumed in DOWNWARD direction?
d. What is the internal moment (KN-m) al midspan if the cutting plane is perpendicular to the floor and assumed in CLOCKWISE direction?

NOTE:Please store values if it is not the final answer. Final answers are in 4 decimal places
