ME 352 - Machine Design I Name of Student___________________________ Spring Semester 2011 Lab Section Number________________________ Homework No. 5 (30 points). Due at the beginning of lecture on Monday, February 21st. Consider the sliding-block linkage shown in Example 2.5, Figure 2.24, page 77, and repeated here as Figure 1. The length of the ground link is 142ROO9 inches==and the length of link 2 is 22ROA4.5 inches.==The position solution for the input angle o2135θ=can be obtained from trigonometry and the answers are 344ROA12.59 inches==and .o3434104.64θ= θ= θ=The angular velocity and the angular acceleration of the input link 2 are 25 k radsω= −/and 2210 k rads ,α=/respectively. The length of link 4 is 4OC20 inches=and note that the origin of the XY reference frame is now chosen to be coincident with the ground pin O2, see Figure 1. Part A.Use the vector loop approach to determine the first-order kinematic coefficients and the
