, 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).
Skeletal muscles that cramp the most often are the calves, thighs, and arches of the foot, and are sometimes called a  Charley horse  or a corkie. Such cramping is associated with strenuous physical activity and can be intensely painful; however, they can even occur while inactive/relaxed.
