SUGGESTED LIST OF STUDENT ACTIVITES

1.       Each student should submit any one of the following type activity or any other similar activity related to the course and before take up get it approved from concerned Teacher and HOD.

2.       Each student should conduct different activity and no repeating should occur

 1 Ask the students to take the simple problems in Strength of Materials, analyze the stresses by using software. 2 Ask the students to take the simple problems in Design of machine elements, analyze the stresses by using software. 3 At least take two simple mechanical components likes step turned shaft, measure the dimensions, Apply loads and analyze for stresses. 4 Study and understand the concept of theories of failure –Maximum shear stress theory, Maximum distortion energy theory ( Von-Mises Theory of failure) 5 Identify the theory of failure for the brittle material and ductile materials

RUBRICS MODEL

 RUBRICS FOR ACTIVITY( 5 Marks) Dimension Unsatisfactory Developing Satisfactory Good Exemplary Student Score 1 2 3 4 5 Collection of data Does not collect any information relating to the topic Collects very limited information; some relate to the topic Collect much information; but very limited relate to the topic Collects some basic information; most refer to the topic Collects a great deal of information; all refer to the topic Ex: 4 Fulfill team’s roles & duties Does not perform any duties assigned to the team role Performs very little duties but unreliable. Performs very little duties Performs nearly all duties Performs all duties of assigned team roles 5 Shares work equally Always relies on others to do the work Rarely does the assigned work; often needs reminding Usually does the assigned work; rarely needs reminding Normally does the assigned work Always does the assigned work without having to be reminded. 3 Listen to other Team mates Is always talking; never allows anyone else to speak Usually does most of the talking; rarely allows others to speak Talks good; but never show interest in listening others Listens, but sometimes talk too much Listens and speaks a fair amount 2 Average / Total marks=(4+5+3+2)/4=14/4=3.5=4

Note: This is only an example. Appropriate rubrics/criteria may be devised by the concerned faculty (Course Coordinator) for assessing the performed activity.
