Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because The system is unbalanced Resonance is caused due to the heavy mass of the rotor The shafts are rotating at very high speeds Bearing centre line coincides with the axis The system is unbalanced Resonance is caused due to the heavy mass of the rotor The shafts are rotating at very high speeds Bearing centre line coincides with the axis ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the crank is at the outer dead centre, in a reciprocating steam engine, then the acceleration of the piston will be ω² r {(n + 1)/n} ω² r {n/(n - 1)} ω² r {(n - 1)/n} ω² r {n/(n + 1)} ω² r {(n + 1)/n} ω² r {n/(n - 1)} ω² r {(n - 1)/n} ω² r {n/(n + 1)} ANSWER DOWNLOAD EXAMIANS APP
