Important questions
share it a link alone
Don't share as screenshot kind request
Don't waste my hardwork and valuable time
Unit-1
1. Selection of V belt drive and it problems
2.flat belt drive problem
(1st unit contain basis problem only)
Unit-2
1.spur and helical gear problems
Unit -3
1.bevel and worm gear problems
Unit -4
1.Variable speed gear box problem
Unit -5
1.clutch problems (or) break problems
(Fully problematic paper so major topic only study)

**Very important questions are bolded and may be asked based on this topic
PART-C
1.Compulsory Questions {a case study where the student will have to read and analyse the subject }
a situation given and you have to answer on your own
don't waste my hardwork and valuable time
As Engineer i think you know how to respect another
Share it as link alone . don't share it as screenshot or any text material if u found this anywhere kindly report me . #Admin WhatsAppContact uS
*These questions are expected for the exams This may or may not be asked for exams All the best.... from admin Santhosh
Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorSYllabuS
