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 sinφ + sinα = b/c cosφ - sinα = c/b tanφ + cotα = b/c cotφ - cotα = c/b sinφ + sinα = b/c cosφ - sinα = c/b tanφ + cotα = b/c ANSWER DOWNLOAD EXAMIANS APP
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 × CN ω² × CO ω² × NO ω² × QN ω² × CN ω² × CO ω² × NO ANSWER DOWNLOAD EXAMIANS APP
