Unformatted text preview: ). CO represents the acceleration of C towards O and NO
represents the accleration of P towards O. The acceleration of other points such as D, E, F and G etc.,
on the connecting rod PC may be found by drawing horizontal lines from these points to intresect CN
at d, e, f, and g respectively. Now dO, eO, fO and gO respresents the acceleration of D, E, F and G all
towards O. The inertia force acting on each point will be as follows:
Inertia force at C = m × ω2 × CO
Intertia force at D = m × ω2 × dO
Intertia force at E = m × ω2 × eO, and so on. Fig. 32.11. Inertia bending forces. The inertia forces will be opposite to the direction of acceleration or centrifugal forces. The
inertia forces can be resolved into two components, one parallel to the connecting rod and the other
perpendicular to rod. The parallel (or longitudinal) components adds up algebraically to the force
