Calculation Example – Plane stress.

Calculate the stresses acting on an element oriented at an angle θ= 60° from the x axis, where the angle θ is positive when counterclockwise. 

An element in plane stress is subjected to stresses ?x = 1000 psi, ?y= 2000 psi, and txy = 2500 psi, as shown in the figure. Calculate the stresses acting on an element oriented at an angle ?= 60° from the x axis, where the angle ? is positive when counterclockwise.
