Hanging Bridge Lab Work

  Data: We used weights varying from 0 g up to 300 g with a 50 g interval between each measurement  Graph: Our graph using the data we collected is shown above. The curve fit was a sin graph.  Our predicted curve fit was a tangent graph. Problem Write up for Blog: Where do the two curves match?   The two curves match when little mass was added to the middle (M) Where do the two curves start to diverge from one another?   Once the mass in the middle was around 150g we started to see the slope of our best fit line decrease and not align with our predicted behavior What does this tell you about the system?  The equation we derived is in a situation that we have a perfect pulley. But in the real world, the pulley has rotational inertia and friction that we need to consider. What are the limitations on the accuracy of your measurements and analysis? Some limitations can include measurement error, as we cannot get an accurate measurement with just our e...

Incline Track

Image
You will have a meter stick, a stopwatch, cart masses and wooden blocks to create the incline. You may also use the video analysis equipment to estimate the effect of friction for measuring the efficiency.  Predictions Make a drawing of the cart on the level track before and after the impact with the bumper.  Define your system. Label the velocity and kinetic energy of all objects in your system before and after the impact. Write an expression for the efficiency of the bumper in terms of the final and initial kinetic energy of the cart. Write an expression for the energy dissipated during the impact with the bumper in terms of the kinetic energy before the impact and the kinetic energy after the impact. Whiteboard Question:  How will friction effect your result?  Even Table Hints:  Find a useful range of heights and inclined angles that will not cause damage to the carts or bumpers. Make sure that the cart will never contact bumper (end stop) during the impact. ...
