Theory of Machine A machine mounted on a single coil spring has a period of free vibration of tp . If the spring is cut into four equal parts and placed in parallel and the machine is mounted on them, then the period of free vibration of the new system will become tp /16 tp /4 4 tp 16 tp tp /16 tp /4 4 tp 16 tp 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 l₁ = kG l₂ = kG l₁l₂ = kG² l₁l₂ = kG l₁ = kG l₂ = kG l₁l₂ = kG² ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base) cotφ - cotα = c/b cosφ - sinα = c/b sinφ + sinα = b/c tanφ + cotα = b/c cotφ - cotα = c/b cosφ - sinα = c/b sinφ + sinα = b/c tanφ + cotα = b/c ANSWER DOWNLOAD EXAMIANS APP
