Answers for Engineering Trivia Challenge Round 2
Mechanical Engineering
What type of stress occurs when a force attempts to twist an object?
Torsional stress develops when a force acts to twist or rotate an object around its axis, such as when using a wrench to turn a bolt.
What type of coupling is used to connect shafts that may become misaligned during operation?
Flexible couplings absorb misalignments and vibrations, extending equipment life in industrial applications.
Electrical Engineering
What type of power supply circuit converts AC to DC?
A rectifier allows electrical current to flow in only one direction, converting AC to DC.
What type of motor is most commonly used in variable speed industrial applications?
VFD motors adjust speed and torque efficiently, making them ideal for industrial applications.
Materials Engineering
What property describes a material's ability to deform under stress and return to its original shape?
Elasticity allows materials to recover their shape when stress is removed.
Which of the following metals has the highest electrical conductivity?
Silver has the highest electrical conductivity, but copper is more commonly used due to cost and durability.
Chemical Engineering
Which separation process uses differences in boiling points to separate liquid mixtures?
Distillation separates liquid mixtures by heating them to their boiling points.
Civil Engineering
What type of joint is used to allow thermal expansion in long pipelines?
Expansion joints accommodate thermal movement in pipelines.
Industrial Engineering
What type of inventory management system triggers orders when stock reaches a predetermined minimum level?
Reorder point systems maintain optimal stock levels by triggering new orders at a set threshold.
What is the meaning of life?
