2. A torsional system with discs of moment of inertia I₁ and I₂ as shown in the below figure, is gear drivensuch that the ratio of speed of shaft B to shaft A is 'G'. Neglecting the inertia of gears, the equivalent14. The equation of motion for a vibrating system with viscous damping is(d²x/dt²) + (c/m).(dx/dt) + (s/m).x = 0, if the roots of the equation are __________ then the system willbe under damped.
When a body is subjected to transverse vibrations, the stress induced in a body will beThe critical speed of a shaft with a disc supported in between is equal to the natural frequency of thesystem inIn steady state forced vibrations, the amplitude of vibrations at resonance is __________ dampingcoefficient.
Equal toDirectly proportional toInversely proportional toIndependent ofWhen there is a reduction in amplitude over every cycle of vibration, then the body is said to haveFree vibrationForced vibrationDamped vibrationUnder damped vibrationThe tractive force in a locomotive with two cylinders is given by (where c = Fraction of reciprocating partsper cylinder, m = Mass of reciprocating parts, ω = Angular speed of crank, r = Radius of crank, and θ =Angle of inclination of crank to the line of stroke)m.ω².r cosθc.m.ω².r sinθ(1 - c).m.ω².r (cosθ - sinθ)m.ω².r (cosθ - sinθ)
