04/ A porter governor is arranged as shown in figure. The rotating masses are each 3kg. The sleeve, of mass 1kg, actuate a lever, which has a mass of 2kg, its, centre of mass being as marked, and which must exercise an operation pull, P, of 25 N. The frictional effect of the gear reduced to the sleeve may be taken as 18 N. Determine the central mass, M, with which the sleeve must be loaded so that the governor is on the point of moving out from the given position at 180 r.p.m. Compute the speed at which it would being to move in from this position. Any formula used must be established. Note: N.B. Moment must be taken about the top pivot of forces on the upper arm. 150mm centre of mans je 225 mm 125 mm 75 mm 225mm
