A force of 120 lb is applied to the edge of the member shown in the figure below. Neglect the weight of the member and determine the state of stress at points B and C using the superposition. 120 lb 4.5 in. | 4.5 in. -2.5 in 2.5 in B.

Problem 3: The rod below has a diamter of 2 in. Determine the state of stress at point A, and show the results on a differential element located at this point. 400 lb x B 500 lb Z A 800 lb 10 in. 15 in.

The answer should be in kN.

Problem 2: A state of plane stress at a point on the surface of a structure consists of the following stress components: Ox = 18 ksi, oy = 24 ksi, and Txy = 15 ksi. Note that the stress components act in the directions shown on the element below. Ox Txy 24 ksi бу 18 ksi 15 ksi (a) Draw a complete Mohr's circle for this stress state. Clearly label the X and Y faces, the center C, and the radius R. (b) Using Mohr's circle, determine the stress components Ox, Oy, and Txy on an element rotated 25° counter-clockwise from the original element shown. Label all of these quantities on the circle. (c) Show all stresses from part (b) on a properly oriented stress element. Be sure to include all stress components acting on the element.

Member AC is subjected to the loading shown in the figure below. Determine the force P if the position x-120 mm of this force so that the average compressive stress at the smooth support C is equal to the average tensile stress in the tie rod AB. The rod has a cross sectional area of 350 mm²2 and the contact area at C is 600 mm² B P C A x=120 mm X 200 mm

The four bars shown have the same cross-sectional area. For the given loadings, show that (a) the maximum compressive stresses are in the ratio 4:5:7:9, (b) the maximum tensile stresses are in the ratio 2:3:5:3. (Note: the cross section of the triangular bar is an equilateral triangle.)
