ME 352 - Machine Design I Name of Student ___________________________ Fall Semester 2011 Lab Section Number ________________________ Homework No. 5 (30 points). Due at the beginning of lecture on Wednesday, September 28th. Consider the inverted slider-crank linkage shown in Problem 3.15, see Figure P3.15, page 160. For the given position of the linkage, the angular velocity and angular acceleration of the input link 2 are specified as 2 10 rad s ω= / clockwise and 2 2 5rad s α= / clockwise, respectively. Determine the following: (i) The first and second-order kinematic coefficients of the mechanism.

(iii) The unit tangent vector and the unit normal vector to the path of point B. Show the directions of these two unit vectors on a sketch of the mechanism. (iv) The radius of curvature of the path of point B. Indicate your answer on a sketch of the mechanism. (v) The X and Y coordinates of the center of curvature of the path of point B. Indicate the position of the center of curvature of the path of point B on a sketch of the mechanism....
