Please see the attached file for the problem and figure.


Homework Equations



The Attempt at a Solution


This is what I have so far:
The position vector of the block, pblock= xblock wx+ yblock wy
pblock dot omegaz=0 holonomic constraint equation (dot product)
n=3N-M
N= # particles=1 block
M=# holonomic constraint equations=1
So, n=3-1=2
For the nonholonomic constraint eq.:
ur=sum Ars us + Br, with r=p+1, ..., n
Ars and Br are functions of the parameteres q1 (usually angle), q2, ..., t (time)
p=# deg. of freedom
ur=generalized speeds

For part c), I wrote omega1 r1=omega2 e => omega2=omega1 r/e=10 r/e
Thank you in advance!

What is the definition of dynamics?

Dynamics is the branch of mechanics that deals with the study of forces and their effects on motion, as well as the relationships between matter and energy.

What is a holonomic constraint equation?

A holonomic constraint equation is a mathematical expression that describes a relationship between the coordinates of a system, such that the system's motion is restricted to a specific path or surface.

What is a nonholonomic constraint equation?

A nonholonomic constraint equation is a mathematical expression that describes a relationship between the velocities of a system, such that the system's motion is restricted to a specific direction or range of velocities.

How do holonomic and nonholonomic constraint equations differ?

The main difference between holonomic and nonholonomic constraint equations is that holonomic constraints restrict the system's motion in terms of coordinates, while nonholonomic constraints restrict the system's motion in terms of velocities.

What is the significance of constraint equations in dynamics?

Constraint equations play a crucial role in dynamics as they provide a mathematical framework for analyzing the motion of constrained systems. They allow us to model and predict the behavior of complex systems, such as mechanical systems, in a systematic and efficient manner.
