Three forces are applied to the machine component ABD as shown in Figure 2. Knowing that the cross section containing point H is a 20 x 40 mm rectangle, determine the stresses at point H. Y 50 mm 150 mm 40 mm 0.5 kN 20, mm 3 kN 160 mm 2.5 kN Figure 2.

Two vertical forces, each of magnitude P = 22 kips, are applied to a beam of the cross section shown. Determine the maximum tensile and compressive stresses in portion BC of the beam.      The maximum tensile stress is  ksi. The maximum compressive stress is  ksi.

The strain rosette shown was used to obtain normal strain data at a point on the free surface of a machine component. Given the values = -165 µμe, e = -155 μe, e = 50 μe, E = 10,600 ksi, and v=0.33, determine (a) the stress components o,,o,, and ry at the point. (b) the principal stresses and the maximum in-plane shear stress at the point; on paper, show these stresses on an appropriate sketch that indicates the orientation of the principal planes and the planes of maximum in-plane shear stress. (c) the magnitude of the absolute maximum shear stress at the point. 45° 45°

Determine the stress state at point H (H has sides parallel to the x and y axes). b. Draw a Mohr's circle representation for the point. What are the principal stresses at point H. 10 in. 4 in. y B 18 in. 1.2 in. P x
