(Equation 10.2: Angular velocity) Step 5 – What is the connection between the instantaneous velocity of a point on the rotating disk and the disk’s angular velocity? The instantaneous velocity of a point is called the tangential velocity, , because the direction of the velocity is always tangential to the circular path followed by the point.

The tangential velocity of the blades, hence MT, is limited by the strength of materials at high temperature, so it may seem that we would like to use small R to maximize the temperature drop per stage.

Find: The magnitudes of the boat’s velocity and acceleration at the instant t = 3 s. Plan: The boat starts from rest (v = 0 when t = 0). 1) Calculate the velocity at t = 3s using v(t). 2) Calculate the tangential and normal components of acceleration and then the magnitude of the acceleration vector.

Velocity: Given a graph of the position function y t of an object, the velocity v t at time t0 is the slope T of the tangent line at P t0, y t0 (the limit of the slopes of the secant lines).

An astronaut is being tested in a centrifuge. The centrifuge has a radius R and, in starting from rest at t = 0, rotates with a constant angular acceleration α = 0.25 rad/s2 . At what time t > 0 is the magnitude of the tangential acceleration equal to the magnitude of the radial acceleration (i.e. centripetal acceleration)?

A vortex sheet is a model for a shear layer. The layer is approximated by a surface of zero thickness across which the tangential velocity is discontinuous, as illustrated in Fig. 5(a). In this case the dispersion relation reduces to w(k) =

Since proper motion is an angular velocity, we also need to know the star’s distance to find its real velocity across our line of sight, called its tangential velocity (vt). Two stars with the same proper motions can have vastly different tangential velocities, as shown in the example in figure below.

The acceleration of a fluid particle is the rate of change of its velocity. In the Lagrangian approach the velocity of a fluid particle is a function of time only since we have described its motion in terms of its position vector. ˆ + yp (t)j ˆ + zp (t)k ˆ. r p = xp (t)i.

Velocity components are taken in the x-z coordinates normal and tangential to the shock, as shown. The tangential z axis is tilted from the upstream flow direction by the wave angle β, which is the same as the Mach angle only if the shock is extremely weak. For a finite-strength shock, β > . The upstream flow velocity components are u1 = V1 ...

Example. That circulation is a measure of rotation is demonstrated readily by considering a circular ring of fluid of radius R in solid-body rotation at angular velocity Ω about the z axis. In this case, U = Ω × R, where R is the distance from the axis of rotation to the ring of fluid. Thus the circulation about the ring is given by:

The tangential velocity is then simply a constant γ/2 directed clockwise around the sheet. By taking the difference between the upper and lower points at some x location,we obtain a very general tangential-velocity jump condition for any vortex sheet in any situation.
