The uniform pressure theory gives a higher frictional torque than the uniform wear theory.
-
The train value of a gear train is
-
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 C Q NO. The acceleration of the piston P with respect to the crankpin C is given by
-
The driving and driven shafts connected by a Hooke's joint will have equal speeds, if
-
The coriolis component of acceleration is taken into account for
-
The frictional torque transmitted in a flat collar bearing, considering uniform wear, is (where r1 and r2 = External and internal radii of collar respectively)
-
The inertia force is equal to the accelerating force in magnitude, but opposite in direction.
