Which direction does torque go?
Torque has the direction perpendicular to the plane of the twist. The Right-Hand Rule says positive torque is counterclockwise(ccw).
How do I know the direction of the torque acting on coil whether its vertical or horizontal?
To know the direction of the torque acting on the coil, whether the coil is vertical or horizontal, you will compare the direction of the magnetic force or its rotation to the direction of the coil. If the coil is vertical and the magnetic force is in the direction of the coil rotation, then the direction of the torque will be the same.
What is net torque?
Net torque is the magnitude and direction of torque that is left over when you add up the torques that are acting on an object.
What is the difference between breakaway torque and rotational torque?
Breakaway torque is the torque required to start the initial movement, in the loosening direction, of a bolt, screw, or nut from its (non−loaded) at rest position with the locking element engaged. Tightening torque is the torque necessary to move the bolt, screw, or nut along its threaded length in the tightening direction.
Why does a bar magnet placed in S-N direction turn towards N-S direction when torque acting on it is zero?
If the bar magnet turned then there was a torque acting upon it. Torque is defined as a turning force or moment.
In what direction should a force be applied to produce maximum torque?
In a perpendicular direction to the rotating body.
Is torque is a scalar or a vector quantity?
Since torque is a force, and as such has a direction, it is a vector.
Why clockwise torque is negetive?
convention, they could have picked either direction.
What is physical significance of torqe?
Torque is rotational force, it makes things change direction.
What are the examples for vector quantities?
A vector quantity is any quantity in which a direction is relevant. Some examples include position, velocity, acceleration, force, momentum, rotational momentum (the vector is defined to point in the direction of the axis in this case), torque, etc.
Is anti clockwise torque negative?
Depends how you define it. For a particular problem, you can arbitrarily define one direction as positive, in this case, the other direction is negative.
Why does my 115v motor start in different directions each time it's energized?
It's due to the cheap design of the motor. When the motor stops, there is some torque being applied to it against the direction that it was moving. The more torque being applied, the more energy is required to get it rotating. So since there is torque in one direction, it will require less energy to get going in the opposite direction of that last time it was running, therefore to save money, it's better to have it turn the opposite direction. A better, more expensive motor will be able to easily supply enough energy to overcome the torque being applied after it stops, so it can always move in one direction.
