Show that the distance from the top of the cylinder to the piston surface in a conventional engine is given by: R² 4L x=r(1-cos)+(1-cos 20) where is the crankshaft angle, R is the length between the main bearing and the big end bearing and L is the distance between the centres of the connecting rod. Comment upon the accuracy of the equation stated in part (a). Discuss how the piston motion can be employed to determine the slider crank piston force.
