Fundamentals of Mechanical Engineering
Question | Answer |
---|---|
Force | A push/pull on an object resulting from its interaction with another object. (Force unit = Newton (N)) |
Force Equation | F = ma - Force (N) = - Mass (kg) x - Acceleration (m/s2) |
Work | Defined as “Force through distance” |
When a body moves under the influence of a force, work is done” | Work = force x distance |
Energy unit | Joule |
Different Energy Forms | 1)Potential Energy 2)Kinetic Energy |
Power? | Rate of doing work |
Power equation | Power = force x average velocity P = F x v |
Unit Power | Watt |
Torque is measured in? | N.m. Sometimes kg.m. |
Torque created around an axis | Moment |
