Torque Flashcards
What causes a rotation?
When a force is not directed through the center of mass of an object
What is Torque?
An applied force that produces a rotation; product of a force and perpendicular distance
How can two forces prevent rotation without being directed toward the center of mass?
If the forces are parallel and of suitable magnitudes
What is a Fulcrum?
Fixed pivot point; where something rotates about/around
What is an example of a fulcrum?
The axis/middle of a seesaw
What is best torque equal to in static equilibrium?
Zero; Σclockwise torque= Σcounterclockwise torque
What is Moment Arm Distance or Lever Arm?
The perpendicular distance from the axis of rotation to the line of action (pivot point/center of mass to force)
What is the equation of Torque?
τ=Fd (if F=0, τ=0)
Units= N*m
Torque is a ________ quantity.
Vector; clockwise= negative, counterclockwise= positive
In order for there to be torque, force and distance must be _____________.
Perpendicular
What is the equation for a balanced torque between two forces?
F1d1=F2d2
If F1 > F2, what is the relationship between their distances from the pivot?
d1
