The graphs below show the angle domain equations for a constant rod length (6.0") and various values of half stroke (1.8", 2.0", 2.2"). Note in the graphs that L is rod length l {\displaystyle l} and R is half stroke r {\displaystyle r} .
On the top is the time-position diagram. Objects representing tautochrone curve A tautochrone curve or isochrone curve (from Ancient Greek ταὐτό ( tauto- ) 'same' ἴσος ( isos- ) 'equal' and χρόνος ( chronos ) 'time') is the curve for which the time taken by an object sliding without friction in uniform gravity to its lowest ...
The problem with this definition is that it does not give the direction of the torque but only the magnitude, and hence it is difficult to use in three-dimensional cases. If the force is perpendicular to the displacement vector r , the moment arm will be equal to the distance to the centre, and torque will be a maximum for the given force.
Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...
The balance wheel and spring function similarly to the torsion pendulum above in keeping time for the watch. The D'Arsonval movement used in mechanical pointer-type meters to measure electric current is a type of torsion balance (see below). A coil of wire attached to the pointer twists in a magnetic field against the resistance of a torsion ...
is the mechanical torque supplied by the prime mover in N-m; is the electrical torque output of the alternator in N-m; Neglecting losses, the difference between the mechanical and electrical torque gives the net accelerating torque . In the steady state, the electrical torque is equal to the mechanical torque and hence the accelerating power is ...

The moment of force, or torque, is a first moment: =, or, more generally, .; Similarly, angular momentum is the 1st moment of momentum: =.Momentum itself is not a moment.; The electric dipole moment is also a 1st moment: = for two opposite point charges or () for a distributed charge with charge density ().
