In particular, when a and [beta] are both 1 in Equation 8, this becomes a problem finding a closest point on the solution set from a target angular acceleration. Furthermore, the calculation method is categorized into two types: finding the foot of a perpendicular line on an unsatisfied boundary and finding an apex of two unsatisfied boundaries.
A (rad/s) [d.sup.2][alpha]/ The angular acceleration of cable AE around d[t.sup.2]: p.
Where: M--Torque [Nm], I--inertia [kg[m.sup.2]] and [epsilon] angular acceleration [rad/[sec.sup.2]].
The angular acceleration, which is obtained by approximating the derivation and applying Euler's rule, can be computed as follows:
However, there are also magnetic fluid accelerometers that can measure both linear acceleration and angular acceleration. Figure 19 presents one of them [35].
Also, the angular velocity, angular acceleration, and translational acceleration of the chassis were determined to analyze the machine's dynamic equilibrium.
Based on Newton's second law of motion, the extrinsic muscles in the forearm must exert a force proportional to the angular acceleration (rotational inertia) of the hand.
Based on model created, differential equations gained, and simulations, results are achieved for main dynamic parameters, shown with their symbols and units as follows: Velocity v (m/s), Acceleration a (m/[s.sup.2]), Angular velocity m (1/s), Angular acceleration aa (or [alpha]) (1/[s.sup.2]), Force F (N), Torque T (Nm), Motion or length s (m).
The CDF is an evolved damping force in a linear function of the half-car body pitch angular acceleration and only supplements the front and rear quarter-car suspension damper forces with the same magnitude but an inverse phase.
As to the fact that the electrical torque of an induction machine is not able to be measured by the electrical units of current and voltage, the only possibility is to measure the shaft torque and the angular acceleration [2, 3].
The angular velocity ([omega]) and angular acceleration ([alpha]) of the pelvis rotation was calculated using the following equations:
