Question

Piston’s axis is horizontal. Resistance force F is applied to piston only during those motion stages, which correspond to reduction of chamber’s volume. But in motion stages, corresponding to increase of chamber’s volume, it is considered that force F = 0.

Moment of inertia of wheel 1 is equal to J1. Weights of mechanism’s members are as follows: connecting-rod 2 – G2; piston 3 – G3. Connecting-rod 2 is assumed as a homogeneous rod with length l and weight G2.
For mechanism’s position corresponding to the given value of angle α it is necessary to
reduce all masses and forces to wheel 1 which angular velocity is assumed as ω.

For mechanism’s position corresponding to the given value of angle α it is necessary to reduce all  

masses and forces to wheel 1 which angular velocity is assumed as ω.

Given:
α = 60º
J1 = 15 kgm^2
G2 = 75N
G3 = 40N
F = 1.5kN
R = 0.6 m
l = 0.8m
OA = 0.25m

Determine reduced inertia I_red and reduced Moment of forces M_red.
