Theory of Machine When the crank is at the inner dead center, in a reciprocating steam engine, then the acceleration of the piston will be ω²r. n/(n - 1) ω²r. (n + 1)/n ω²r. n/(n + 1) ω²r. (n - 1)/n ω²r. n/(n - 1) ω²r. (n + 1)/n ω²r. n/(n + 1) ω²r. (n - 1)/n ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A body in motion will be subjected to Coriolis acceleration when that body is In plane rotation with variable velocity Restrained to rotate while sliding over another body In plane motion which is a resultant of plane translation and rotation In plane translation with variable velocity In plane rotation with variable velocity Restrained to rotate while sliding over another body In plane motion which is a resultant of plane translation and rotation In plane translation with variable velocity ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/4 Become equal to 2R Become equal to R/2 Remain same as before Become equal to R/4 Become equal to 2R Become equal to R/2 Remain same as before ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The minimum length of the coupler will be 45 mm 95 mm Slightly more than 45 mm Slightly less than 45 mm 45 mm 95 mm Slightly more than 45 mm Slightly less than 45 mm ANSWER DOWNLOAD EXAMIANS APP
