Theory of Machine A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear driven such that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent inertia of disc on shaft B at the speed of shaft A is equal to G².I₂ G.I₂ I₂/G² I₂/G G².I₂ G.I₂ I₂/G² I₂/G ANSWER DOWNLOAD EXAMIANS APP

The frequency of motion is given by (where δ = Deflection of the spring) 1/2π. √(δ/g) 2π. √(δ/g) 2π. √(g/δ) 1/2π. √(g/δ) 1/2π. √(δ/g) 2π. √(δ/g) 2π. √(g/δ) 1/2π. √(g/δ) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2 mm 3.0 mm 2.50 mm 2.22 mm 2 mm 3.0 mm 2.50 mm 2.22 mm ANSWER DOWNLOAD EXAMIANS APP
