Theory of Machine A rigid body, under the action of external forces, can be replaced by two masses placed at a fixed distance apart. The two masses form an equivalent dynamical system, if The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The center of gravity of the two masses coincides with that of the body The sum of the two masses is equal to the total mass of body All of these The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The center of gravity of the two masses coincides with that of the body The sum of the two masses is equal to the total mass of body All of these 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 Remain same as before Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ + ω₂)r (ω₁ - ω₂)r (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ + ω₂)r (ω₁ - ω₂)r ANSWER DOWNLOAD EXAMIANS APP
