EMAE 181 – Dynamics
Homework #7 – Vector Chain Derivatives
Due Friday 2
nd
week of class
The disk rolls without slipping on the surface.
At the instant shown, the disk has an
angular velocity of 20 rad/s CW and an angular acceleration of 5 rad/s
2
CCW.
Fill out
the chart on the following page similar to how we did in class on Tuesday.
Determine the
velocity and acceleration of pin
A
with respect to the slotted member
BC
and the angular
velocity and angular acceleration of arm
BC
.
Let
r
= 0.2m.
Neglect the distance from the
center of pin
A
to the edge of the disk.
