A differential elements on the bracket is subjected to plane strain that has the following components: ϵx = 150(10 −6 ), ϵy = 200(10 −6 ), γxy = −700(10 −6 ). Use the strain-transformation equations and determine the equivalent in plane strains on an element oriented at an angle of u = 60° counterclockwise from the original position. Sketch the deformed element within the x – y plane due to these strains. image is uploaded for reference.

Solid Mechanics

Engineering mechanics is a branch of science that deals with forces causing bulk motion in bodies and the effect that these forces cause on the bodies. Engineering mechanics does not deal with the internal changes that occur on account of these external forces. The internal effects in a body or a material under the action of external forces are studied in a new branch of science called solid mechanics, the strength of materials, or the mechanical behavior of engineering materials.
