Match each mechanical loading scenario with the most appropriate fastener or joint design.
- A temporary joint that must act as a freely pivoting point and withstand pure double-shear loading without axial tension.Clevis pin secured with a cotter pin
- A permanent, aerodynamic joint for thin sheet metal subjected strictly to single-shear forces and high vibration.Solid shank flush-head rivet
- A structural joint requiring high clamping force (pretension) to transmit loads via friction and prevent slip under dynamic forces.High-strength bolt and nut with specified torque
- A joint designed to lock a rotating hub to a shaft to transmit rotational torque while preventing independent rotation.Woodruff key
Answer
The double-shear pivot requires a clevis pin, the aerodynamic shear joint requires a flush rivet, the high-friction structural joint requires a high-strength torqued bolt, and the rotational torque joint requires a Woodruff key.
Each fastener type is engineered for a distinct loading profile. Clevis pins provide unthreaded double-shear pivots. Rivets provide permanent single-shear strength. Torqued bolts provide the axial tension needed for friction joints. Woodruff keys handle rotational torque on shafts.
Step-by-Step Solution
Key Concept
Matching fastener design and joint geometry to specific mechanical loading conditions such as pure shear, axial tension, friction transmission, and rotational torque.
