Question

The figure below shows a device driven by a carne. When rising, the cam has a polynomial The rising angle is B 160° The descent profile is cycloidal, and the descent angle is profile 3-4-5 for which the course S (measured in m) is given below (one in the up position also B 160 The cam has two rest periods of 10 and the other in the down position center of rotation of the cam that the stiffness constant of the sp ). If the axis of the pusher passes through the ring is K N/m, that the displaced load has a weight of P N, and that at the lowest position, the spring is cornpresse of a length x m, formulate the power relationship that will allow to choose the engine to drive the came speed con stante. Also indicate two angular positions () likely to maximum power demanded. Justify your choices with a complete demonstration. Consider that the system does not have a flywheel, neglect the effect of friction as well as all forces other than the load P Comment and describe your situation (in words). se.sin 2Movement cycloidal S h 10 15 Mouvement polynomial 3-4-5 poussoir
