, 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.

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).
Similarly, the muscles that maintain our posture contract and relax in a synchronized fashion. A muscle that involuntarily contracts without our consciously willing it is called a spasm.. If the spasm is forceful and sustained, it becomes a cramp. A muscle cramp is an involuntarily and forcibly contracted muscle that does not relax. Muscle cramps 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.
