Since you have not mentioned the name of the exam in which you have got this rank I consider your exam to be  TNEA.

considering the previous year TNEA cutoffs and your rank , you do not have chances to get a seat in this college  but considering your community rank , you can  have  some chances of getting a seat in mechanical engineering  .Since cutoffs fluctuate every year ,nothing can be  predicted with full assurance .This is just a prediction on the basis of the previous year cutoffs so don't lose hope.
