A solid rod has a diameter of e = 55 mm and is subjected to the loading shown. Let a = 200 mm , b = 210 mm , c = 310 mm , d = 250 mm , and P = 3.0 kN. Take point A to be at the top of the circular cross-section. (Figure 1)
a. As shown (Figure 2), a cut was made at A to determine the resultant internal loadings. Determine the moment about the x-axis, Mx.
b. To find the state of stress at A, the principle of superposition must be used. If the rod has a diameter of 55 mm, find the stress σA due to the normal force.
c. To find the state of stress at A, the principle of superposition must be used. If the rod has a diameter of 55 mm, find the stress σA due to the bending moment about the x-axis.
d. To find the state of stress at A, the principle of superposition must be used. Find the stress σA due to all of the loadings on the rod.

The formula was put into dimensionless form to answer the following question: What is the shape of the deflection curve when the beam is in its loaded condition and how does it compare with its unloaded perfectly horizontal orientation? The answer is provided graphically in Figure Q4. Figure Q4 shows the vertical deflection of a uniformly loaded cantilever beam and its comparison with the unloaded perfectly horizontal orientation.
