Study Guide: Midterm Exam, ENG 183 SP10
The midterm exam will consist of five problems:
1. An Inventor Rotation Problem (25%)
2. An Inventor Assembly Problem (25%)
3. Tolerancing (15%)
4. Circuits (20%)
5. General questions/Brainstorming/Project Managemen
Constraints and Information Needs
When making the roller coaster, some constraints had to be taken into account. These
constraints include table size, materials given, the inability to strap the ball to the track,
and maximum height of the starting point.

ENG 183: Midterm Review Solutions
Problem #1: CIRCUITS
Find current, voltage, and power across each resistor.
=6
i =i1 = i2= i3 (Current is same through all resistors in series)
i=Vtotal/Rtotal (ohms law)=6/6 =1A
V1 = i1R1 = (1A)*(1) = 1V
Similarly, V2
Eng 183: Midterm Review Problems
Problem #1:
For each circuit (a & b), find the voltage, current, and power across each resistor.
(a)
(b)
Problem #2: Control Circuit
A space heater can be turned ON if a user turns on the manual switch
OR if the thermostat
