10-6. A differential element on the bracket is subjected to plane strain that has the following components: €, = 150(10 6), e, = 200(10 “), Yxy =-700(10 “). Use the strain-transformation equations and determine the equivalent in plane strains on an element oriented at an angle of 0 = 60° counterclockwise from the original position. Sketch the deformed element within the x-y plane due to these strains.

Center of Gravity and Centroid

The term center of gravity indicates the position or location of a point about which the whole weight of a body or system is supposed to be concentrated, which means the whole weight of the body or system works through this point. It is closely related to mass distribution. For all positions of the body, the center of gravity would be a single point.
