Theory of Machine A disturbing mass m₁ attached to the rotating shaft may be balanced by a single mass m₂ attached in the same plane of rotation as that of m₁, such that (where r₁ and r₂ are the radii of rotation of m₁ and m₂ respectively) m₁ m₂ = r₁ r₂ None of these m₁ r₁ = m₂ r₂ m₁ r₂ = m₂ r₁ m₁ m₂ = r₁ r₂ None of these m₁ r₁ = m₂ r₂ m₁ r₂ = m₂ r₁ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine For an involute gear, the ratio of base circle radius and pitch circle radius is equal to sinφ cosφ secφ cosecφ sinφ cosφ secφ cosecφ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A system in dynamic balance implies that The system is critically damped There is no critical speed in the system The system is also statically balanced There will absolutely no wear of bearings The system is critically damped There is no critical speed in the system The system is also statically balanced There will absolutely no wear of bearings ANSWER DOWNLOAD EXAMIANS APP
