Formulation for Changing from Tangential to Cartesian Elements
Changing from tangential to Cartesian elements entails calculating the projection of the tangential vector onto the x-axis and y-axis. The formulation for these projections are:
Vx = V * cos(theta)
Vy = V * sin(theta)
the place:
* Vx is the x-component of the tangential velocity
* Vy is the y-component of the tangential velocity
* V is the magnitude of the tangential velocity
* theta is the angle between the tangential velocity vector and the x-axis
Instance
Contemplate a tangential velocity vector with a magnitude of 10 m/s and an angle of 30 levels with respect to the x-axis. The x-component and y-component of this velocity vector may be calculated as follows:
| Element | Formulation | Worth |
|---|---|---|
| Vx | V * cos(theta) | 10 m/s * cos(30°) |
| Vy | V * sin(theta) | 10 m/s * sin(30°) |
Due to this fact, the x-component of the tangential velocity is roughly 8.66 m/s and the y-component is roughly 5 m/s.
Calculating the Tangential Element
To calculate the tangential element of a vector, we use the system:
$$T = r occasions v$$
the place:
– $T$ is the tangential element
– $r$ is the place vector
– $v$ is the speed vector
The tangential element is a vector that lies within the airplane tangent to the curve on the level the place the speed vector is evaluated. Its magnitude is the same as the pace of the particle at that time, and its path is tangent to the curve.
To use this system, we are able to use the next steps:
1. Discover the place vector $r$ by subtracting the preliminary place vector from the present place vector.
2. Discover the speed vector $v$ by taking the by-product of the place vector with respect to time.
3. Calculate the cross product of the place vector and the speed vector to acquire the tangential element $T$.
We are able to characterize the place vector and velocity vector by way of their Cartesian elements as follows:
| Vector | Cartesian Elements |
|---|---|
| $r$ | $langle x, y, z rangle$ |
| $v$ | $langle v_x, v_y, v_z rangle$ |
Utilizing these Cartesian elements, the tangential element may be calculated as:
$$T = leftlangle yv_z – zv_y, zv_x – xv_z, xv_y – yv_x rightrangle$$
