Thank you so much, Ramnares! That's very good to hear! I would've used a Cd of 2 as well, so that makes me feel better. I will move on and not let it bother me.

Absolutely! Here's the problem verbatim: A 150 lbf cartoons carrier measures 51" long by 35" wide by 18" high. If a 3000 lbf car is driven at 65 mph into a 10 mph headwind, the added net motor power required when the carrier is used is most nearly: I can solve the problem all but an ACCURATE...

Mike, thanks for taking the time to reply! Unfortunately, I'm not sure we're on the exact same page. There are indeed graphs in the MERM that you can find the Cd based on the Re and the Area FOR A GIVEN SHAPE. For example, disk, sphere... But, in this problem we are actually looking for the...

Fellow engineers, I'm working through some practice exams (specifically the Lindeburg Practice Exam) and running into some extremely frustrating issues with assumptions at times. This latest issue is about the morning session's #28. There are several ways of finding the coefficient of drag on...
