What is more damping torque or controlling torque?
Following are the essentials of indicating instruments: 1. Operating torque, 2. Controlling torque, and 3. Damping torque. OPERATING TORQUE Operating torque is produced by making use of any of these effects: magnetic, electromagnetic induction...., it is required to move the moving system of the instrument. CONTROLLING TORQUE Controlling torque opposes the operating torque and increases with the deflection of the moving system. It ensures that the deflection of the pointer is according to the magnitude of electrical quantity being measured. If this torque were not provided, the pointer would continue to move indefinitely and the deflection shall be independent of electrical quantity being measured. It also bring the pointer back to zero when the instrument is removed from the circuit. This torque is either obtained by spring or by gravity. In spring control, one or two phosphor bronze spiral hair-springs are attached to the moving spindle. The other end are attached to the frame. In this case Tc proportional to Angle of deflection. In gravity control, a small weight is attached to the moving system in such a way that it tries to bring the pointer back to the zero position when it is deflected, due to gravity. In this casse Tc proportional to sine of the angle of deflection. DAMPING TORQUE Controlling torque controls the deflection and tries to stop the pointer at its final position where its Td = Tc But due to inertia, the pointer oscillates around its final position before coming to rest. Hence damping torque is provided to avoid this oscillation and bring the pointer quickly to its final position. Thus the damping torque is never greater than the controlling torque. In fact it is the condition of critical damping which is sufficient to enable the pointer to rise quickly to its deflected position without overshooting.
What causes a slanted tv picture?
If the deflection yoke is rotated it can cause a slanted TV picture. The deflection yoke is located on the tube neck inside the TV.
What causes just a thin flat line and nothing else to appear on your tv screen?
The vertical deflection system is broken. The vertical deflection system is broken.
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
What is the torque for the alternator belt in a 1997 Mazda protege?
Tighten the belt until you have 1/2" of deflection at midpoint. I hope this helps you. Mark
What causes accelerated rotation?
Torque does.
What do you mean by torque weight ratio of an indicating instrument?
torque/weight ratio of an instrument indicates sensitivity.if a pointer is having less weight, it will be having high torque/weight ratio so that even for a very small deflection pointer starts moving and indicates measured value.
What causes wind deflection from the North and South poles?
rotation of Earth on its axis=coriolis effect
In the Southern Hemisphere the Coriolanus effect causes winds to curve to the?
left. This is due to the rotation of the Earth causing a deflection in the direction of moving objects, including winds. In the Southern Hemisphere, this deflection results in winds curving to the left.
What causes Deflection?
the main causes of the inflation is increase in the percapita income and this results in increase in the standard of living of the people .. and the other one is increase in the percapita income in our country
What is a torque meter?
A torque sensor, or torque meter, is a device that measures the torque on rotating systems, usually wheels. Torque, in this case, is the twisting force that causes rotation, such as that applied when you pedal a bicycle.
