01/ A porter governor its central load is 18 kg and the weight of each ball is 2 kg. The top armsare 25 cm while the bottom arms are each 30 cm long and all arms pivoted on the axis ofGovernors(Homework's)tation. The friction of the sleeve is 14 N. If the top arms make 45° with the axis of rotation inequilibrium position, find the speed of the governor at that position.021 The four arms of a proell governor are 300 mm long and are pivoted on the axis of rotation.Fach ball weight 5 kg and is carried on an extension 100 mm long of the lower arms. Thecentral load on the sleeve is 80 kg. Calculate the equilibrium speed of the governor to radiusof rotation of 150 mm when the extension arm is vertical.Q3/ A porter governor has equal links, each 250 mm long pivoted at the axis of rotation, each ballis of mass 4 kg and the mass of the central load is 15 kg. The governor begins to lift whenthe ball radius is 150 mm. It has a maximum speed at a radius of 200 mm. Determine themaximum speed, the range of speed, the sleeve lift, the governor effort, the power of thegovernor and governor sensitivity.Q4/ A porter governor have all arms 300 mm long. The upper arms are pivoted on the axis ofrotation and the lower arms are attached to the sleeve at a distance of 35 mm from the axis.Each ball has a mass of 7 kg and load on sleeve is 54 kg. If the extreme radii of rotation ofthe balls are 200 mm and 250 mm. Determine the speed range of the governor and governorsensitivity.Q5/ In a spring loaded Hartnell type of governor, the mass of each ball is 4 kg and the lift of thesleeve is 50 mm. The governor begins to float at 240 rpm when radius of the ball is 110 mm.The maximum speed of the governor is 252 rpm when friction is neglected. The lengths ofthe ball and roller arms of the bell-crank lever are 120 mm and 100 mm respectively. Thepivot center and the axis of the governor are 140 mm apart. Determine the stiffness of thespring.Q6/ Calculate the vertical height (n) or a Watt governor at a speed of 180 rpm and the movementproduced by an increase of 20 rpm. Also find the governor sensitivity.O7I The mass of each ball of a proell governor are 9.6 kg and the mass on the sleeve is 90 kgEach of the arms is 305 mm Tong. The upper arms are pivoted on the axis of rotationubereas the lower arms are attached to a sleeve at a distance of 38 mm from the axis. Themass of the ball is attached to the extension of the lower arms which are 102 mm long, Theminimum radius of governor is 165 mm, assuming that the extensions of the Jower arms arenarallel to the governor axis at the minimum radius, and the maximum radius of governor is540 mm when the upper arms are inclined at angle of 50°, find the corresponding equilibriumO8L The power of a Hartnell governor is 15 W and having a central sleeve spring and two right angledolls crank levers moves between 290 rpm and 310 rpm. The sleeve arms and the weight armsDes cm and 12 cm respectively. The levers are pivoted at 14 cm from the governor axis and thespeeds.aatation if the minimum radius of rotation is 9 cm, (2) stiffness of the spring, (3) centrifugal forcePage 13 of 15Bie the maximum speed are 830 N and 1400 N respectively. Determine the (1) maximum radius
