Theory of Machine In the below figure, PC is the connecting rod and OC is the crank making an angle θ with the line of stroke PO and rotates with uniform angular velocity at ω rad/s. The Klien's acceleration diagram for determining the acceleration of the piston P is shown by quadrilateral CQNO. The acceleration of the piston P with respect to the crank-pin C is given by ω² × QN ω² × CO ω² × NO ω² × CN ω² × QN ω² × CO ω² × NO ω² × CN 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) l₁ = kG l₁l₂ = kG² l₂ = kG l₁l₂ = kG l₁ = kG l₁l₂ = kG² l₂ = kG l₁l₂ = kG ANSWER DOWNLOAD EXAMIANS APP
