Mechanics Flashcards
What is the equation for a turning moment
Moment = force X perpendicular distance
What is mechanical force
Push or pull
What is the SI unit for Force
Newtons (N)
What is the unit for a moment
Newton Metres
What is the principle of moments
Clockwise moments = anti-clockwise moments
What is Newton’s second law
Force= Mass x Acceleration
How do we convert mass into force
F= m x g (where g is acceleration due to gravity)
What is the formula for torque?
Torque = Force x radius x sin ()
Torque is not the same as moments?
True or false.
False - They use the same units and formula
What qualities does a couple have?
- parallel
- Equal magnitude
- opposite direction
What is a Vector
A measurement with magnitude and direction
What is a scalar
A value with only magnitude
Give some examples of a scalar:
Mass Distance Volume Weight Speed
Give some examples of vectors:
Force
Velocity
Acceleration
Displacement
What is Pythagoras theorem
= a ^2+b^2=c^2
