, TEACHING AND EDUCATING SOCIETY, ENLIGHTING THE FUTURE GENERATION. English in engineering comes under EST (English for Science and Technology). Unlike literary English, the joy in this English is its crispness. Writing a novel and writing a technical paper (Thesis etc) has a hell and heaven differences. Basic difference is that a technical writer must target its readers first before he sits for writing.
A cramp is a sudden, and involuntary muscle contraction or over-shortening; while generally temporary and non-damaging, they can cause mild-to-excruciating pain, and a paralysis-like immobility of the affected muscle(s).
A muscle (or even a few fibers of a muscle) that involuntarily (without consciously willing it) contracts is in a spasm.. If the spasm is forceful and sustained, it becomes a cramp. Muscle cramps often cause a visible or palpable hardening of the involved muscle. Muscle cramps can last anywhere from a few seconds to a quarter of an hour or occasionally longer.
