To determine the maximum shear force that can be applied to two shafts of varying cross sections: a solid square shaft and a hollow square shaft.
Learning Goal: To determine the maximum shear force that can be applied to two shafts of varying cross sections: a solid square shaft and a hollow square shaft. The two square cross sections shown below (Figure 1) are each subjected to a vertical shear force, V. The side length of each cross section is s = 6.75 in and the side length of the hollowed-out portion of the second cross section is r = 4.00 in. The maximum allowable shear stress in...

Learning Goal: To calculate the normal and shear stresses at a point on the cross section of a column. The state of stress at a point is a description of the normal and shear stresses at that point. The normal stresses are generally due to both internal normal force and internal bending moment. The net result can be obtained using the principle of superposition as long as the deflections remain small and the response is elastic. Figure < 1 of...
