A series of questions and answers where you have to describe the motion of a pulley, including: - which direction the pulleys in a system are rotating in (clockwise or counterclockwise) based on a information given about the input pulley, - what the ratio is between the input pulley and the other pulleys in a system, using the diameter of each pulley, - and the corresponding torque values. The conclusion questions ask you to describe your understanding of pulleys and sprockets.

Questions (and some answers) regarding simple machine systems. Each question requires proper illustration and annotation, but I didn't do most of those. The calculations involved are: - mechanical advantage, - static equilibrium calculations, - ideal effort force, - and so on.

Answers to a five-part question about setting up an experiment to calculate the spring constant of a spring.

A set of questions we completed for homework in this class.

The document answers these questions for the CHEM 1111 Workshop class (co-requisite to CHEM 1311 at UTD). 1. Draw Lewis structures for the polyatomic ion “hydrogen carbonate” (bicarbonate) and acetic acid. 2. Considering that an acid-base neutralization reaction can be thought of as a “proton transfer reaction” wherein the acid is the proton donor and the base is the proton acceptor, which proton in your Lewis structures above is transferred.

Using the graphs of functions to answer limit questions, and then evaluating limits algebraically.

The first two questions are calculating limits algebraically. The next three questions are a limit of piece-wise functions at critical points and two limits for trigonometric functions.

Evaluating limits. I got the first 14 questions correct. It went downhill with the trigonometric limits, not all of which I answered. I did well with the algebraic limits, though.

I only did one of the questions on these pieces of paper. (The rest of the answers may be somewhere else. I couldn't find it.)

Considering functions defined by its graphs and finding some limits.
