Equilibrium : A state in which opposing forces are balanced.
: An object in Equilibrium will be stationary as there are no Net forces acting on it.
Definition. the turning effect of a force
the distance is between the fulcrum and the line of the force
If a body is in equilibrium,
Forces Up = Forces Down
Forces Left = Forces Right
Moments Clockwise = Moments Anti-Clockwise
Handlebars on bicycles.
Simple experiments with a number of weights.
Appropriate calculations. (Only problems involving co-planar parallel forces need be considered.)
Torque, e.g. taps, doors.
Reference to moving-coil meters
and simple motor.
6. Conditions for equilibrium
The sum of the forces in any direction equals the sum of the forces in the opposite direction. The sum of the moments about any point is zero.
Static and dynamic equilibrium.
