At a point on the free surface of a machine part (E = 214 GPa, G = 83 GPa), the state of the stress is illustrated in the figure below. For the given plane stress condition determine: Show the principal stresses and the max in plane shear stress and the average normal stress on an appropriate schematic

Question 2)  arm of Figure  B  from point x z  plane, a horizontal angle of θ = 38 ° angled F = 29 kN force sized and  C  from the point   z  direction M = 17 kn.m acts a moment in size.   The lengths of the arm are also given as  L 1 = 1.5 m  and  L 2 = 1.1 m  . It is desired to determine the stress state of point A on the aa section taken from the arm. The radius r of the section  is  r=0.015 m  and the shear modulus of the arm material is also G = 78 Gpa . According to this;     Question 2-C) Find the normal stress caused by the normal force   at point A  (  Write your result in  MPa .) Question 2-D) Find the normal stress  caused by the bending moment   at point A. (Your result  MPa  in the size of  your font.)

Please show full work than you

A rectangular column (blue color) is fixed to a rigid ground (brown color). As shown in the figure, the column is under two external loadings at C. Determine the state of stress at point K of the column and represent the stress components on a stress element.

Consider a point in a structural member that is subjected to plane stress. Normal and shear stress magnitudes acting on horizontal and vertical planes at the point are Sy= 41 MPa, Sy = 11 MPa, and S=-44 MPa. (a) Determine the principal stresses (o,l > 02) and the magnitude of the maximum in-plane shear stress Tmax acting at the point... (b) Find the smallest rotation angle 0, (counterclockwise is positive, cločkwise is negative) that will rotate to principal directions. Then show these stresses in an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16) Answers: OpI = MPa. Op2 = MPa. Tmax | MPa.

- once answered Correctly will UPVOTE!!

There’s a force acting in the Y and Z direction

I need the answer as soon as possible

Two forces, 100 kN and 200 kN, act on the rectangular column in the figure. Find the stresses at A and B points according to the given and show them on the stress element.

The state of plane stress at a point on the surface of the airplane fuselage is represented by the stress element shown in the figure. Using Mohr's Circle, determine a) the principal stresses and the maximum in-plane shear stress specifying the orientation of the element in each case. b) The equivalent state of stress at the point on the element that is oriented {a} clockwise from this position Draw all the corresponding stress elements. Given x = {x} MPa; y = {y} MPa and xy = {xy} MPa xy MPa y y MPa 10000 x MPa →→→→x Solve in terms of variables
