ME350 W10 HW #4 [Please note the change in due date and submission location.] Due: Friday, Feb 19 at 3 pm Turn in your homework to a box near the GSI desks at 1210 Dow Print out your work with formula - we will post instructions Problem #1 Analyze the motion of a crank-rocker four bar linkage. The length of the links 1 (ground), 2 (crank), 3 (coupler), and 4 are 10, 2, 7 and 6 mm, respectively. For both open and close forms: At 2 = 0°, calculate angles 3 and 4 and show your calculations. At 2 = 0°, show your calculations to find the coordinates of a coupler point on link 3 with 3 = 45° and p = 5 mm (see the definition of 3 and p in Fig. 4-14). At 2 = 0°, 30°, and 60°, using either Excel or Matlab, plot the configuration of the fourbar linkage. At 2 = 0°, 30°, and 60°, using either Excel or Matlab, plot the locations of the

Unformatted text preview: coupler point on link 3 with 3 = 45° and p = 5 mm (see the definition of 3 and p in Fig. 4-14). At 2 = 0°, 30°, and 60°, calculate the transmission angle. NOTE: Do NOT submit the Excel or Matlab in CTools. Print out your worksheet with formula – to be explained in class. Problem #2 Analyze the motion of VW TDi slider (piston)-crank shaft linkage (the one in the lab) using either Excel or Matlab. The length of the links 2 (crank) and 3 (connecting rod) are 45 and 145 mm, respectively. The offset c is 0.5 mm. For both open and close forms, at 2 = 0°, 45°, and 90°: Calculate the angle 3 and d . Plot the configuration of the slider-crank linkage at these three positions using the Excel or Matlab....
