Use the minimum potential energy method to find the displacement at the midpoint of the rod shown under the body force g. Consider u = a + a2x+a²x² on ad X x=0 Body force per unit volume, pg = 1 E=1 A = 1

The 5.5-kg uniform rod is pinned at end A. It is also subjected to a couple moment of 50 Nm. The spring is unstretched when 0 = 0, and has a stiffness of k = 60 N/m.

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°
