A beam that has a mass of 75kg extends from a building making a 48° angle with it.  A wire is supporting the beam, it is attached to it 3/5 of the way along the beam.  The wire is perpendicular to the wall.  There is also a sign hanging from the end of the beam with a mass of 14kg.  The beams center of mass is 1/4 of the way from the wall to the end of the beam.  What are the x and y components of the force that the wall exerts on the beam? create a extended free body diagram.  Label the axis of rotation on the beam that you will use as reference when measuring distances.

Area Computations

The area is the mathematical estimation of the inner space occupied by any shape or object and area computation is the evaluation of how much inner space that particular shape or object has utilized. Simple applications include calculating the area of wall for the quantity of paint or plaster to be applied on it, area calculations for construction of a trapezoidal dam and how much material is required, calculating the area of a circle to determine the range or distance of wheels that they are capable of covering due to varied radii and so on.
