Video explains concept of kinetic moment as taught in engineering dynamics-hibbeler

Tangential Acceleration is introduced and visualized. Example problem is worked through. We even relate arc length, tangential velocity, and tangential acceleration via the derivative! Example: A record player is plugged in and uniformly...

To find the acceleration of the masses and the tension in the cable I recommend the following steps:

1) Dra
w FBD
2) D
efine axes
3) Apply
newtons 2nd law
4) Find accel

Mass 1 and mass 2 hang from either side of a frictionless #pulley with #rotationalInertia, I, and radius, R. What is the angular acceleration of the pulley? Use #ConservationOfEnergy

1) Calculating if our answer makes sense. 2) Why can’t we sum the torques on everything? 3) Finding the force of tension.

A uniform 0.093 kg meterstick is supported at the 15 cm and 92 cm marks. When a 0.250 kg object is placed at the 6.0 cm mark, what are the magnitudes of the forces supporting the meterstick?

Angular acceleration is introduced by way of linear acceleration. The units of radians per second squared are discussed. Examples of objects which angular acceleration are shown.

A Silent Film in honor of #DayofSilence to clarify the differences between angular, tangential, and centripetal accelerations

We derive both the direction and the equation for centripetal acceleration. Want Lecture Notes?

We determine what data to collect to create a graph with rotational inertia as the slope of the best-fit line. Then we collect the data and determine the rotational inertia of an irregular shape.

Anatomy, course and branches of the vestibulocochlear nerve.

To solve for the acceleration of a point A moving relative to an object that is rotating then we can use the relative velocity (for rotating reference frames) equation:<b<br/>r/>

Aa = Ab + Arel + Ap/b + 2 w x Vrel

The best way to understand how tangential velocity and tangential acceleration are related is to visualize from above. Will you look at that! This video does exactly that.

Find the acceleration of the center of mass of the disk. 1. Use F = ma AND M = I alpha 2. Assume pure roll ie a = r alpha 3. Check validity of assumption ie, F less than Fmax 4. If F less than Fmax, THEN assumption is true 5. If F...

We predict and measure the force of tension acting on a pulley while the system is at rest and accelerating.

What is the angular acceleration of a compact disc that turns through 3.25 revolutions while it uniformly slows to a stop in 2.27 seconds?
