A single cylinder vertical engine has a bore of $300 \mathrm{~mm}$, a stroke of $350 \mathrm{~mm}$ and a connecting rod of length $700 \mathrm{~mm}$. The weight of the reciprocating parts is $125 \mathrm{~kg}$. When the piston is at quarter-stroke from TDC and is moving downwards, the net pressure on it is $0.55 \mathrm{MPa}$. If the speed of the engine is $240 \mathrm{rpm}$, calculate the turning moment on the crankshaft.
