A beam is subjected to a concentrated force, as shown in the figure elow, try to find the Elastic Curve after the beam is stressed, The flexural stiffness of the beam section is constant El: a) When using the Double Integration Method to solve, it is necessa o use the boundary conditions (Boundary Condition) to get the constant term after integration, what are the boundary conditions of this problem? b) Find the elastic curve from point A to point C (x1). c) Same as above, find the difference between point C and point B x2) Elastic curve.

An element in plane stress is subjected to stresses σ_x, σ_y, and τ_xy (see figure). Using Mohr’s circle, determine the stresses acting on an element oriented at an angle θ from the x axis. Show these stresses on a sketch of an element oriented at the angle θ. (Note: The angle θ is positive when counterclockwise and negative when clockwise.) Given: σ_x=33 MPa,σ_y=-9 MPa,τ_xy=29 MPa,θ=35°
