Two metallic plates of thickness e=5 mm are joint together using joint covers of the same thickness t=2,5 mm and width b=5 cm. Other dimensions of the joint are given by: s=1 cm and r=1 mm. The joint is realized with four screws without pretensioning of diameter 8 mm. The screw holes have a diameter that is one millimeter larger than the diameter of the screws. The admissible shear stress in screws or plates is Tadm=110 MPa, the admissible compressive...

3- The shaft shown in the figure rotates with constant angular velocity and is transmitting a torque from gear B to gear C through the forces Exo and Ez as shown. The shaft is subject to combined bending and torsion due to the forces shown. The weights of the shaft and pulleys may be neglected and the supports can exert only concentrated force reactions. The radius of the gear at B is 50 mm and that at C is 75...
