Question

mm in the dledtio tional area oftA=100 mm2and a modulus of elasticity 200 GPa. Bar AP and bar BP have lengths of 14P= mm and LBp 250 mm, respectively. Use the logic in Fig- , gation of the 3.8 The tapered b that varies tion of the b ure 3.2, to determine the applied force F. 30° 750 Figure P3.3 Figure w the shear stress due to torsion on the stress cubes at points A and B in Figure P3.4. Is the shear stress positive or negative ty or r 3.4 Dra 3.9 The radius (r/LX2L rotation shaft. Figure P3.4 Figu 3.10 Deter umn in, t 120 i are in 3.5 Draw the shear stress due to torsion on the stress cubes at points 4 and B in Figure P3.5. Is the shear stress positive or negative

Answer 1

Shear stress is on positive x-face and in negative z direction therefore negative shear stress shear stress is on positive x-face and in positive y direction therefore positive
