Figure 5 shows a metal cutter that used to cut the cable at C. The jaws J are pinned at E, A, D and B. There is also a pin at F. (a) Determine the force developed on the cable at C and pin A if force 200 N is applied to the handles. (b) If the force exert on the cable C has to be maintained as in (a) and the force applied to the handle to be reduced by 20%, redesign the dimension of the cutter. Prove your answer with calculation. mm 20 A D 80 mm/ 400 mm 20 mm 120 120 20 mm 400 mm Figure 5 [Rainh SI 120 1200 N 20 200 N
