Can you choose any pivot point?
The choice of pivot point (that is, reference point) is arbitrary. But that choice can make the work of getting to the answer harder or easier just in terms of the number of manipulations needed in the math. Pivot points are among the oldest and most effective trading techniques used.
Can torque be calculated about any point?
You can use whatever point to compute the angular acceleration AT THIS POINT. If your problem ask you to compute angular acceleration without specifying at which point, then you must assume at which point it is, probably the one having special caracteristics depending on what the context is.
Do professional traders use pivot points?
Due to their high trading volume, forex price movements are often much more predictable than those in the stock market or other industries. The professional traders and the algorithms you see in the market use some sort of a pivot point strategy.
What is the most accurate pivot indicator?
Short time frames like 1-minute, 2-minute and 5-minute are the best for pivot point indicator. This makes pivot points more preferable to day traders. Pivot point indicators are amongst the best tools when accuracy is concerned. This is because of the fact that pivot points are so widely used.
How do you know the direction of rotation?
This direction can be determined using the right hand rule, which says that the fingers on your hand curl towards the direction of rotation or force exerted, and your thumb points towards the direction of angular momentum, torque, and angular velocity.
How do you find the direction of torque in an electric field?
τ = (q E sinθ) d = q d E sinθ If the direction of an electric field is positive, the torque is in the clockwise direction (therefore negative) in the above figure.
Does torque depend on reference point?
If the total force is non-zero, then your torque depends on the reference point. Note that a non-zero torque not necessarily implies angular acceleration – or even that the angular acceleration is in the same direction as the torque.
How do you calculate rpm torque?
- Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
- Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
- Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
- Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.
Does pivot point affect torque?
A force applied to an object can produce a torque, which depends on the location of the pivot point.
Is moment the same as torque?
Torque is considered the force that rotates the body about the axis. A moment is the force that causes the body to move (not rotate).
Why is there no torque at the moment of a pivot?
This is due to the definition of the moment arm, which is the distance between the pivot point and the point where the force acts. If the force acts right on the pivot point, then r = 0, so there would be no torque.
What is the CW torque at the pivot point?
If you keep the left side, to have equilibrium, at the pivot point you will have to have a force of magnitude F acting down, plus a CW torque of value F ( E + L) − F E = F L, because the reaction force is also generating torque. So for the A = 0 case the torque is augmented by a factor of E + L L.
How do you calculate torque on a torque wrench?
You press down on the wrench at a distance L from the pivot point with a force F, which is compensated by the nut with an equal but opposite force F at a distance E from the pivot point. The total torque generated by this two forces is F(E + l) CW, which is compensated by an equal but CCW torque from the nut.
How do you find torque from force and distance?
Another way of expressing the above equation is that torque is the product of the magnitude of the force and the perpendicular distance from the force to the axis of rotation (i.e. the pivot point). Let the force acting on an object be broken up into its tangential ( F t a n) and radial ( F r a d) components (see Figure 2).
