significantly. Thestudents were surveyed on the following questions regarding agile practices: Q-A1: “Working in pairs on this project was challenging.” Q-A2: “Having bi-weekly gate presentations to briefly discuss the progress in team project helped me to be more engaged in the group's progress and makes team work and communication between the students and the instructor more transparent.”The survey results show that only 20% of students found working in pair to be challenging,which was previously pointed out by students as a main challenge during the second yearimplementation of the design project (only PBL). This was complemented by the results of thesecond question where 80% of students found the bi-weekly gate presentations

Also, in the special case with Fa  0 , determine the natural(undamped) frequency n for small-amplitude oscillations of the system due to gravity alone.Constraints and RelationsBased upon the rolling-without-slipping condition for the disk on the support surface, it is foundthat the kinematics and relative positions of various points on the system are governed by xP  rd   vP  rd   aP  rd  (31) rQ/P   12 lb [sin  i  cos  j] , rC/P   rd j (32)where points P and Q identify the respective mass centers of the disk and bar, and C identifiesthe point of contact
