problem $1$

In the two$-$cycle piston engine shown, explosive gases are ignited in the combustion

chamber above the piston. The explosions apply a force of $100$ N for the duration of every

downward stroke. The engine is equipped with a speed limiting device $($rev limiter$)$ which

prevents the rotational speed from exceeding a set value $($red$-$line$).$ The masses of the piston

and connecting rod are $1$ kg and $2$ kg $,$ respectively. The mass of the crankshaft$-$flywheel

assembly is $35$ kg $.$ Given that the red$-$line of the engine is $),$ detemine

the forces at the crankshaft bearing $($point A $)$ and connection rod $($point B $)$ bearing.
