Exercise 6: Force transfer in steam engine In a steam engine the steam force \( \vec{D} \) is redirected to the crank force \( \vec{K} \) tangential to the circular motion of the crank. Study the mechanism for the case that the steam engine runs so slow that accelerating forces can be neglected \( \left(m \ddot{\vec{r}}_{i} \approx 0\right) \). Use D'Alembert's principle to derive an expression for the magnitude of the force \( K \) as function of the magnitude of the steam force \( D \) and the angle \( \alpha \).
