Term
 Sprocket
Definition
 A toothed wheel whose teeth engage the links of a chain.
Term
 Static Equilibrium
Definition
 A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
Term
 Technical Communication
Definition
 Creating, designing, and transmitting technical information so that people can understand it easily and use it safely, effectively, and efficiently.
Term
 Torque
Definition
 A force that produces or tends to produce rotation or torsion.
Term
