Theory of Machine When the load on the engine increases, it becomes necessary to increase the supply of working fluid and when the load decreases, less working fluid is required. The supply of the working fluid to the engine is controlled by a D-slide valve Governor Meyer's expansion valve Flywheel D-slide valve Governor Meyer's expansion valve Flywheel ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A system of masses rotating in different parallel planes is in dynamic balance if the Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant couple is equal to zero Resultant force and resultant couple are both equal to zero Resultant force is equal to zero Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero Resultant couple is equal to zero Resultant force and resultant couple are both equal to zero Resultant force is equal to zero ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The essential condition of placing the two masses, so that the system becomes dynamically equivalent, is (where l₁ and l₂ = Distance of two masses from the centre of gravity of the body, and kG = Radius of gyration of the body) l₁l₂ = kG l₁l₂ = kG² l₂ = kG l₁ = kG l₁l₂ = kG l₁l₂ = kG² l₂ = kG l₁ = kG ANSWER DOWNLOAD EXAMIANS APP
