Test 1

Lab[edit | edit source]

Go over test?

Report longer than a half page.

Do assigned circuit

Make a quick circuit diagram.

Most important part: Document with greek letters.

Thursday:

Group reports encouraged.
You must do the assigned circuit, unless you choose to do no circuit.
Most of the time, you can do a report on something else.
Choices: Previous test or Area of a sphere using calculus.

_____

  1. Answer without using calculus
  2. Do a first order approximation (whisky-cigar w/o the cigar) and compare the answers.
  3. Can you define an intrinsic variable for the bent/wrinkled tape?

Set the radius at the free-throw be nominally R= 2m and let the tape width be W=4cm. Express all your equations using the symbols (R,W) in order to app

Lab and Recitation Hours[edit | edit source]

Algebra
  • Lab1 110 min
  • Rec 55 min
  • Lab2 110 min
110<Total<275

Note that 275/5 = 55

55-10 = 45 minutes

Lets do projects and split into 5 groups
Lab1 45 min (X 2 shifts)
Rec 45 min
Lab2 45 min (X 2 shifts)

Halfway between 3:20 and 5:20 is 4:20



Two lab periods every day
3:20 - 4:20 You can come 15 minutes late or leave 15 min early.
4:20 - 5:20 You can come 15 minutes late or leave 15 min early.
Recitation group
5:30 - 6:25 You can come 10 minutes late or leave 10 min early.
We will have 5 groups
  1. Early Tuesday Lab
  2. Late Tuesday Lab
  3. Recitation Tuesday
  4. Early Thursday Lab
  5. Late Late Thursday Lab

Projects[edit | edit source]

The goal of each project is co-authorship on the Lake Campus Research Symposium

Conceptual technical writing[edit | edit source]
Optics and manufacturing[edit | edit source]
Radioactive decay, statistics, and computer programming[edit | edit source]
Mathematical physics[edit | edit source]
  1. Why is useful if not true
  2. Generalizing the Taylor expansion to two dimensions
  3. Calculating the area of a sphere and how that eventually led to a precise definition of temperature and entropy
Creating exam questions[edit | edit source]
Mechanics, music and measurement of time[edit | edit source]
Gridion pendulum and properties of materials[edit | edit source]
Physics 1110 labs[edit | edit source]
  1. Force table w Escel and error analysis
  2. Stretching a long string
  3. Others are possible

1 A cylinder of radius, R, and height H has a uniform charge density of . The height is much less than the radius: H << R. The electric field at the center vanishes. What formula describes the electric field at a distance, z, on axis from the center if z > H/2?

b)
c)
d) none of these are correct
e)

10-15T (week8)[edit | edit source]

Start lab schedule[edit | edit source]

  • Unless I change my mind, you are all allowed to do this lab by doing an assigned lab and the report. The only complication is that I might not have enough "traditional" labs for you to do. I might be forced to make you do one of my projects on one or two lab sessions.
For that reason, I need a list of people who wish to do a project leading to a symposium poster.
  • There is a shortage of people who want to do the Thursday late lab (4:25-5:20) due to a difficult class that follows. We will devote that time-slot to a project related to materials, and set aside time for study if you have an exam just after the test.
  • I have two "engineering projects":
  1. Upside down goggles
  2. Gridiron pendulum: wikipedia:Gridiron pendulum and also Lake Campus Gridiron page
