- Read the question carefully and give me answer according to the question. The state of stress at a point is shown on the element. Determine (a) the principal stress and (b) the maximum in-plane shear stress and average normal stress at the point. Specify the orientation of the element in each case. Sketch the results on each element. Solve the problem using the formula comparing to Mohr’s Circle. Oy=160 MPa , Txy=120 MPaYoung modulus and stress have same dimension. a.True b.falseThe stress–strain diagram of the material can be approximated by the two line segments. If a bar having a diameter of 80 mm and a length of 1.5 m is made from this material, determine the critical load provided the ends areixed. Assume that the load acts through the axis of the bar. Use Engesser’s equation.
- please i need help for this question. The stress element is shown in the figure. Determine the equivalent stress according to the third and fourth strength theory.1- Determine the orientation measured clockwise to the principal plane (in degrees). 2- Transform the state of stress shown by rotating its orientation 50 degrees counterclockwise. What is the normal stress (in MPa) on the face which originally had the 75 MPa compressive stress (i.e. the top and bottom of the element). Make sure to enter a positive answer if it is in tension and a negative answer if it is in compression.The given stresses are 0x = 48 MPa, 0x =- 32 MPa, and Txy = 20 MPa. The rotation angle 0 = 30°.Use the stress transformation equations to determine the stresses on an element that is rotated bythe given angle 0 and show the calculated stresses on the rotated element.
- The state of stress at a point is shown on element. Determine principal stressSchematically find the normal and shear stresses in the plane when the element given in the form of plane stress is rotated 30 degrees clockwise with the Mohr circle.The state of stress on an element relative to the xy-axis is presented above. The element is to be reoriented as shown. a) What are the components that describe its original state of stress (??, ??, ???) and what is the angle of rotation (?)? Make sure your signs are correct. b) Using the equations of stress transformation, determine ??′, ??′, and ??′?′ and draw these components of stress on the rotated element. c) What are the principal stresses and angles of the principal planes? What is the shear stress associated with this orientation? d) What is the maximum in-plane shear stress and the angle of its associated plane? What are the associated normal stresses in this orientation? e) What is the absolute maximum shear stress and what plane (xy, xz, or yz) does this stress act upon?

Apply the concept of analytical method to find stresses acting on an element oriented at 30° counter clockwise with respect to the original element.Calculate the principal normal stress values, the principal normal stresses and the stresses that will occur on the inclined (C) surface of the stress element whose stress state is given in the figure, using the ANALYTICAL METHOD.
