1. Construct a composite shape using at least 4 commonly used shapes. Each shape can be additive or subtractive to the total area. Then, determine the following: a.Area of each shape b.X and Y measurements of the centroid of each shape c.Total area of the composite shape d.X and Y measurements of the centroid of the composite shape       2. Construct a distributed load using at least 3 commonly used shapes. Each shape can be additive or subtractive to the total load. The distributed load is supported by a beam with a pin and a roller. Then, determine the following: a.Equivalent concentrated load of each shape b.X and Y measurements of the centroid of each shape c.Determine the reaction (magnitude and direction) on the supports (pin and roller).
