Exercise 6: Force transfer in steam engine In a steam engine the steam force 13 is redirected to the crank force If 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 (m- % 0). 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 0
