1. (50 pts) The following solid shaft has a diameter of 36mm. Its right end is connected to a gear with a diameter of 160mm. The gear is applied with two external forces. One force (640N) is applied on the gear surface in the negative y-direction, and the other force (5000N) is applied at the gear center in the negative x-direction. The right figure shows the shaft cross-section at Point K and Point H. ער 160 mm H H 640N K K d=36mm 500 mm 5000N a) Determine all the internal loading components (including axial force, bending moment, twisting moment, etc.) on the cross-section containing Point K and Point H. b) Determine the normal stress and shear stress at Point K. c) Determine the normal stress and shear stress at Point H. d) Determine the principal stresses within the x-y plane at Point K. Assuming the following is the original coordinate system, draw the new coordinate system after rotation to reach the principal stress at Point K. у Z
