Explanation Given information: The diameter of the beam is 450 mm. Calculation: Sketch the free body diagram of the beam as shown in Figure 1. Take moment about A . ∑ M A = 0 B y ( 4 ) − 12 × 6 − ( 8 × 4 × 2 ) = 0 4 B y − 72 − 64 = 0 B y = 34 kN Summation of vertical force is zero. ∑ F y = 0 A y + B y = 8 × 4 + 12 A y + 34 = 32 + 12 A y = 10 kN Sketch the calculated values as shown in Figure 2. Calculate the shear force as follows: Calculate the shear force at point A . S F @ A = 10 kN Calculate the shear force at point B . S F @ B = 10 − 32 = − 10 kN Calculate the shear force at point C . S F @ C = 10 − 32 + 34 − 12 = 0 Sketch the shear force diagram as shown in Figure 3. Calculate the bending moment as follows: Calculate the bending moment as follows: B M @ A = 0 Calculate the bending moment at point x . B M @ x = 10 × 1.25 ( − 8 × 1.25 × 1.25 2 ) = 12.5 − 6.25 = 6.25 kN ⋅ m Calculate the shear force at point B . B M @ B = 12 × 2 = 24 kN ⋅ m Sketch the bending moment diagram as shown in Figure 4. The maximum moment is 24 kN ⋅ m . Calculate the moment of inertia ( I ) of the cross section about the neutral axis as shown in below: I = b 1 d 1 3 12 − b 2 d 2 3 12 Here, b 1 , b 2 is the width of the section 1,2 and d 1 , d 2 is the depth of section 1,2
