Grading: 

Homework solutions will be posted one week later. 
Policies:
Homework: Homework is assigned on Wednesday and due at the beginning of class the following Wednesday. Late homework will be marked down 10% a day for a week (after that, since the solutions will be posted, they will have no value). The homework is a tool for learning; while you may work together in solving them, copying is not condoned. See HW Writeups below for presentation style.Examinations: It is expected that the Johns Hopkins ethical standards apply: www.advising.jhu.edu/ethics.html
There will be two hour exams:the first on Thursday February 22 and the second on Tuesday, March 20.These will be given during the regular class time. The final exam time is on the morning of May 9th. Each exam will be comprehensive, covering material from previous exams as well as new material.Laboratories: There will be three formal labs given through the semester. Participation in and writeup for each lab will contribute 5% of the final grade.The class will be divided into groups of 4 members or less; each lab will have an experimental component and a laboratory component.Labs will be offered over a twoweek period, (Th 1112; Th 121; Th 34; Th 45; F 1112; F 121; F 34; F 45) with individual writeups due one week later. The labs are here in pdf format: Constrained Rectilinear Motion, Energy, Impulse and Momentum, and RigidBody Kinematics.
Thursday Classes: The Thursday class will be used for a variety of purposes throughout the semester.Many weeks, it will be used as a recitation session wherein additional examples will be worked, "problem areas" addressed, and assistance with homework problems given as necessary.Other weeks, it will be a regular class. It IS considered a regular class period.
HW Writeups: Clarity of presentation is very important in engineering calculations, as others must be able to follow and verify your work in order to avoid costly mistakes. In the event of a failure, engineering calculations are carefully scrutinized and can be admitted as evidence in court. For these reasons, and others, it is important to develop good techniques of organization and presentation in solving problems. Please observe the following guidelines in presenting your work; failure to do so will result in deduction of points.
Web Resources: There are a variety of web sites that offer online instruction or instructional applets. A listing of such sites is given by www.engr.umd.edu/HAMLET/resources.htm
 Use engineering paper or white ruled 8.5" by 11" paper, with no spiral edges
 Use a sharp (or mechanical) pencil rather than pen, and erase mistakes rather than crossing them out; make sure that your lettering is neat and legible.
 Write only on one side of each sheet of paper.
 Write your name and the page number (e.g., 1/5 or 1 of 5) at the top of each page.
 Don't crowd your work on the page, and leave at least one blank line between distinct problems.
 Begin each solution with a statement of the problem, including sketches showing the geometry and dimensions of the system, and freebody diagrams as appropriate.
 Along with the mathematical details of your solution, present a concise narrative explaining what you are doing.
 Carry out the solution in symbolic form, and do not substitute numerical values until the final step of the solution.
 Highlight your answers by underlining them or drawing a box around them; always include appropriate units for numerical values.
