- 39 - Supplemental Exercise Problems for Chapter 3 Problem 3.1 For the mechanism shown, write the loop equations for position, velocity, and acceleration. Show all angles and vectors used on the drawing and identify all variables. For the position defined by the data below, find 1 4 v C and 1 4 a C if link 2 rotates with constant angular velocity. AB BC = = = ° = 1 4 90 1 cm, cm, , ˙ rad/ s θ θ A B 2 C 3 4 θ Problem 3.2 In the mechanism shown, ˙ φ is 10 rad/s CCW. Use the loop equation approach to determine the velocity of point B 4 for the position defined by φ = 60˚. 3 4 φ 2 10 inches B Problem 3.3 In the mechanism given, 1 v B 2 is 10 in/s to the right (constant). Use the loop equation approach to determine 1 v A 4 and 1 a A 4 . Use point O as the origin of your coordinate system. 30˚ A B 2 3 4 1 v B 2 AB = 10 inches O

### 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.
