(7) An aluminum alloy block is fixed to two rigid plates at its top and bottom surfaces, respectively, as shown in the figure below. If the top plate displaces 1 mm horizontally when it is subjected to a horizontal force P = 500 kN while the bottom plate is stationary. The width of the block is 10 mm. Using the energy method, which of the following values is correct for the strain energy stored in the block material? -400 mm P= 500 KN 200 mm (A) 300 Nm (B) 500 Nm (C) 250 Nm (D) 150 Nm
(8) A force of 10 kN is applied to a cantilever beam through a handle, as shown in the figure below. Which of the following statements is incorrect for this beam? 6 mm 51 mm 200 mm D 10 KN 150 mm H B (A) The external force load induces equal torsion shear stress at point H and point K. (B) The external force load does not induce bending shear stress at point H. (C) The external force load does not induce bending shear stress at point K. (D) The external force load induces compressive stress at point K due to bending.
