Lab 3 Report
Section 03: Constant Acceleration:
Dry Ice Puck on a Ramp
Pivot Interactivities
Giselle Paz

PHYS 1403
INTRODUCTION
In this lab, we learn how to construct a velocity vs time graph. To do this, we watched an
interactive video that displays a dry ice puck sliding on an aluminum ramp. In addition,
we learn how to analyze a position vs time graph with a non-constant velocity, linearize
data, generate a mathematical relationship between position and time, and make
predictions regarding the puck’s motion.
MATERIALS
In this lab experiment, we used the following materials:
●
Dry Ice Pucks
●
Aluminum Ramp
●
Stopwatch
●
Protractor
●
Ruler
PROCEDURE
1.
Allow video to play and watch phenomena (dry ice puck sliding down the
aluminum ramp).
2.
(Set the video to Mass A and ramp angle #9) Use the tool icon, select the stopwatch
and reset. *
Note: if we want a position vs time graph for the sliding puck on
the ramp, we cut to frame 42 (ribbon no longer is attached to puck)
. After, find
the angle of the ramp using the protractor tool, and measure.
*Angle measure:
22 degrees
3.
Use the ruler tool and measure how far the puck travels to the bottom of the
ramp.
*Measurement:164 cm
4.
Now you can choose a mass and ramp angle; I chose
Mass D: 25 g and Ramp
Angle #9.
With the mass and angle, we will be recording our data into a table to
later create a graph. Continue this process until the puck has reached the bottom
of the ramp at time intervals of 0.1s.
DATA & DATA ANALYSIS
Table and Graph 1:
The table below shows our recorded data of all the
positions and times
until the
puck
had reached the bottom of the ramp.
We recorded the time from
0.1s
to
0.9s

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…

ECO
5. AUTOMOTIVE. The power an
engine produces is called
horsepower. In mathematical
terms, one horsepower is the
power needed to move 550
pounds one foot in one
second, or the power needed
to move 33,000 pounds one
foot in one minute. Power, in
physics, is defined simply as
the rate of doing work. The
formula below gives the
horsepower at 5,252 radians
per second.

In the automotive industry, supercars are highly accredited with how they are manufacture; from the
type of car chassis used to the type of materials employed. Often enough, companies like BMW,
Mercedes & Audi produces supercars that exemplifies a better reliability compared to other automotive
manufacturing companies. This is because they pay close attention to the details on how the car is
manufactured; right from raw materials to a finished supercar. The task given to you is to watch the
video link provided below & explain the electrostatic process acquired for the two different models of
BMW vehicles.
