Welcome!

Welcome to the ME 274 blog. This blog is a complement to the lecture book for the course. Please review the resources that are available to you in the links on the left sidebar of the blog. Please use the discussion thread below to interact with your colleagues and friends in the course in learning the course material.

The blog is currently under construction for the Summer 2020 term. The material will ready for the start of classes on June 15.

Homework H1.B

 

OBSERVATIONS: From the above simulation of the motion of P, we can make a number of observations:

  • The velocity of P is always tangent to the path of P; the acceleration is NOT tangent to the path. Do you know why?
  • The acceleration of P is strictly in the y-direction. Why is that? (It is given that x_dot = constant, therefore x_dotdot = 0.)
  • The acceleration of P has a constant magnitude. Can you see that from your analysis?
  • Although x_dot is a constant, the speed of P is not constant; in fact, the speed decreases as P moves in the positive y-direction, and increases as P moves in the negative y-direction. Can you see this in your analysis?

We are encouraging you to communicate with us and with your colleagues in the class through the threaded discussions on the course blog. If you have questions on this homework, please ask here.
