Unformatted text preview: COE 2001 — Test 2 — Fall 2006 Name: PLEASE NOTE: 1. S"??? If axes are speciﬁed for a given problem, you are to use them. Do not change them in any way or you get a 0 (zero) to that question. Show all work. Provide units with your answers, and box them. Deﬁne clearly any new variable you introduce in a problem based on the givens. For the ﬁrst problem, you are to use vectors to solve it, i.e. write forces and moment arms as vectors and calculate moments using cross products. Failure to comply will result in a 0 to the question even if you arrive at the right answer in some diﬂerent manner. Pb. I (50 pts) — A 40-kg cover for a roof opening is hinged at corners A and B. The roof forms an angle of 25° with the horizontal, and the cover is maintained in a horizontal position by the brace CE. Assume that the hinge at A does not exert any axial thrust. a— Draw a complete FBD on a separate picture. Fully label all forces and indicate the direction they’re pointing to clearly. b- Solve for the force exerted by the brace. —-—’ = CCl)O) 6?— EQws&§/_IMRY)Q-3> Pb 11 (50 pts) — a- Specify your x and y axes clearly. b- Use the method of joints to solve for the force in member GF, and indicate whether GF is in tension or compression. 4 c— Use the method of sections to solve for CB and AC. Indicate whether they are in tension or compression. ' ,/ = 3 xi 5) Ten: thz é——"'—* T 6’“ 1 RM ’ Te? ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
