We will use both shearing and bearing analysis to determine the quantities of rivets needed to fasten BC and BE. We can determine two values then choose what will be more safe. ■ For Member BC: ■ Based on Shearing: V T == ■ Av Based on Bearing: P Ab 70MPa = 96000 N .n.

If we only use 5 rivets, then the bearing stress will become 168.42 MPa. It will result to failure since the allowable bearing stress is only 140 Mpa. ■ For member BE: (Practice at Home) Pac EXAMPLE: 5.

A cable is attached to the beam a distance l2 from the hinge to help support the beam. The cable makes an angle 0 with the beam as shown. e 4 Paul's o o. Auto Repair E A 13% Part (a) On the following free body diagram, draw all of the forces acting on the beam, representing the forces as vectors. Use a coordinate systen with the x-axis on the horizontal (along the length of the beam) and the y-axis vertical (perpendicular to the beam). Use "wb" for the weight of the beam, "ws" for the weight of the sign, "FT" for the force of tension, and "H" for the force on the hinge. Finally, since we don't know the angle that the force on the hinge will act based on the diagram alone, let it be acting at an angle be denoted "o" from the positive y-axis.

H.W: Design a knuckle joint for a tie rod of a circular section to sustain a maximum pull of 70 kN. The ultimate strength of the material of the rod against tearing is 420 MPa. The ultimate tensile and shearing strength of the pin material are 510 MPa and 396 MPa respectively. Determine the tie rod section and pin section. Take factor of safety = 6.
