Abdul Samad kholia axk168131 Problem 3: a) This sketch is not fully defined. It has 37 DOF and some constraints already applied. To fully constraint the sketch, we have to provide 13 dimensions . This was verified using CAD software as well. Explanation: 37 total DOF coincident: 8 * 2 DOF = 16 horizontal: 4 * 1 DOF = 4 tangent: 4 * 1 DOF = 4 37 - (16+4+4) = 13 dimensions needed. b) The total number of Degrees of freedom of the sketch without any dimensions or constraints imposed are 37. Explanation: 2 arcs: 2 * 5 DOF = 10 1 circle: 1 * 3 DOF = 3 6 straight lines: 6 *4 DOF = 24 Total DOF = 10 + 3 + 24 = 37 DOF .
