A hand truck is used to move two barrels, each weighing 80 lb.
Neglecting the weight of the hand truck, determine (a) the vertical force P
which should be applied to the handle to maintain equilibrium when
α = 35°, (b) the corresponding reaction at each of the two...

I had this exam question for a final exam and I was wondering if I got it right or not. There are three point charges +4q equally spaced apart at the tips of an equilateral triangle with distance .11m apart from each other. What is the magnitude of the electric field at the...
I'm taking chemical engineering thermodynamics right now and I'm a little confused about Carnot and Rankin Cycles and some other stuff. I was wondering what are some good resources like books, video lectures, online notes, etc... that help explain the formulas and how they're derived and just...
What sort of stuff that's covered in P-Chem that's not covered in Quantum Mechanics (I plan on taking both Quantum Mechanics I&II if I don't take P-Chem). What are the advantages of taking P-Chem when you're taking going to take Quantum?
Thanks in advance!
I'm not sure whether to just take Physical Chemistry because I'm interested in it or should I just take Quantum Mechanics? I've already taken Thermodynamics and I heard P-Chem is Thermo and Quantum combined. Is Quantum more in-depth than P-chem?
What sort of goals? I'm just curious.
Also to the OP, yes GPA is pretty important in college. Make sure you do well and don't be afraid to ask questions or go to tutoring or the professors' office hours if you don't understand. I had to learn the hard way.
Also, GPA is important for...
I'm using Introductory Chemical Engineering Thermodynamics now but I feel like it doesn't contain enough worked out problem. Can anyone recommend a good Thermodynamics book with tons of examples, explanations and problems that I can check my answers too?
Anyone like the Thermodynamics REA...
My current major is BME (Biomedical Engineering):
What I like:
-PHYSICS (EVERYTHING ABOUT PHYSICS) esp. Quantum Mechanics and Theoretical Physics!
-Chemistry (Molecular chemistry: why and how they react. Quantum Chemistry, etc... Particle Chemistry).
-Biology (Mostly cellular and...
Griffiths only uses calculus III? I've taken it already, so it should be okay. I'm just afraid it'll be too advanced physics wise? What's different about his book that the other books don't have?
I Love Lewin! Definitely checking it out :D
The first semester of college I did okay but I messed two semesters afterward.
I've learned:
-To stop caring about what other people think (Spent too much time with friends)
-To stop taking a FULL load of classes
-To stop procrastinating and cramming
I know I can do well in my major (BME)...
I just read chapter 16 of Serway yesterday and I was confused as to where he got a lambda for his equation. Then I referenced University Physics and he didn't use lambda, he used something else and it made sense to me. I like University Physics better, it's more practical and it gives you good...
I'm going to take a course on Biophysics next semester but there's no textbook. I heard it's because the professor is really good.
Here's the description:
Introduction to the structure, properties, and function of proteins, nucleic acids, lipids and membranes. In depth study of the...
Oh noes, why do I need to remember Torque?
And about my name, I have been told it's from Naked Lunch but no, I just borrowed it from Harry Potter haha. But it just means a neutral person in politics.
