Question

The figure below depicts the cantilever beam. Determine the magnitudes of bending moment (M) in kNm, axial stress() in kN/m2, and shear force (V) in kN acting at point A. The equation for finding the axial stress is = Axial load / cross-section area. Cable XX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXI BT Beam (0.2 m × 0.2 m) Frictionless Pulley 3 m 50 kN Select one: a Bending moment (M) = 150 kNm, Shear force = 50 kN and axial stress = 1250 kN/m2 b. Bending moment (M) = 225 kNm, Shear force = 75 kN and axial stress = 1500 kN/m2 c. Bending moment (M) = 100 kNm, Shear force = 300 kN and axial stress = 1750 kN/m2 d. Bending moment (M) = 75 kNm, Shear force = 25 kN and axial stress = 1000 kN/m2

Answer 1

Given. Cantilever beam. FBD of Beam. Since radius of pulley is not given so neglecting 3m T = 50KN SO, Bending moment ad A = 50x3 = 250 kN- Shear force = 50KN Caxial stress - Faxital Facial = I - Area &0.200.2 so, axial stress - 50 = 1250 kN/732 so, option @am Area KN mer SO KN-m Stoess Ti sie. BM = 150 kN-m , Shear force = 50 kn, gaval = 22505 (M)
