PROBLEM 15.193
The L-shaped arm BCD rotates about the z axis with a constant
angular velocity @₁ of 5 rad/s. Knowing that the 150-mm-
radius disk rotates about BC with a constant angular velocity
@2 of 4 rad/s, determine (a) the velocity of Point A, (b) the
acceleration of Point A.
Answers:
V₁ =-(0.600 m/s)i + (0.750 m/s)j - (0.600 m/s)k
a=-(6.15 m/s²)i- (3.00 m/s²)j

At the instant considered the radar antenna shown rotates about
the origin of coordinates with an angular velocity
@ = ai + @j+wk Knowing that (VA) = 15 in./s,
(VB), 9 in./s, and (VB), = 18 in./s, determine (a) the angular
velocity of the antenna, (b) the velocity of point A.

Answers:
=
(0.600 rad/s)i - (2.00 rad/s) j + (0.750 rad/s)k
V₁ = (20.0 in./s)i + (15.00 in./s) j + (24.0 in./s)k
