I. Briefly answer the following questions 1. The graph below shows a treadle operated grinding wheel operated by a fourbar linkage. The link of length 0.13 m is attached to the wheel. A force F is applied to the treadle link to drive the grinding wheel. a) Can the wheel make a full revolution? Why? b) How many toggle positions are there? Sketch the linkage when it is in a toggle position. (3pts) Label the length of each link. (2pts) c What are the transmission angle and mechanical advantage when the linkage is in its toggle position? (2pts) 0.75 m 0.13 m 0.9 m 0.6 m
