MECHANICAL ENGINEERING TERMS
QUESTIONS VERIFIED ANSWERS|100%
CORRECT|GRADE A+
Mechanics - ANSWER the study of objects at rest or in motion, the effects of forces on a body, and the
prediction of motion
First Law of Thermodynamics (Newton) - ANSWER A body at rest or in constant motion remains in that
state until acted upon by an external form
Second Law of Thermodynamics - ANSWER An unopposed force causes a mass to accelerate
Third Law of Thermo - ANSWER Every force action has an equal and opposite reaction
Statics - ANSWER Study of forces acting on a non-accelerating body, reaction of that body (nothing is
accelerating, forces = 0)
Dynamics - ANSWER Study of motion of a body, in translation and rotation
Dynamic analysis - ANSWER Force = mass x acceleration
Types of loading - ANSWER 1. tension 2. compression 3. moment 4. shear
Tension - ANSWER pull apart, pull on both joints
Compression - ANSWER push together, push on both joints
Moment - ANSWER rotation
Shear - ANSWER distort shape
