Step 1

Since the beam is fixed at C, it will have a vertical reaction force \( R_C \), a moment \( M_C \), and a horizontal reaction force \( H_C \). However, there are no horizontal loads, so \( H_C = 0 \). Show more…

Figure 3 shows a cantilever beam ABC with a fixed support at C, loaded with a concentrated 8 kN force at A and a linearly distributed load varying from zero to 30 N/mm between B and C. The cross-section, also shown in the figure, is a hollow rectangle. The material has a Young's Modulus of 200 GPa. Calculate: (i) The internal shear forces and bending moments along the beam. (ii) The maximum bending stresses. (iii) The displacement of point A.
