In a spring-loaded governorof the Hartnell type, thelengths of the horizontal andthe vertical arms of the bell-crank lever are 40 mm and 80 mm respectively.The mass of each ball is 1.2 kg. The extremeradii of rotation of the balls are 70 mm and 105mm. The distance of the fulcrum of each bell-crank lever is 75 mm from the axis of rotation ofthe governor. The minimum equilibrium speed is420 rpm and the maximum equilibrium speed is4% higher than this. Neglecting the obliquity ofthe arms, determine the(i) spring stiffness,(ii) initial compression, and(iii) equilibrium speed corresponding to radiusof rotation of 95 mm.

Three 25-lb rotor disks are attached to a shaft that rotates at 720 rpm. Disk A is attached eccentrically so that its mass center is in. from the axis of rotation, while disks B and C are attached so that their mass centers coincide with the axis of rotation. Where should 2-lb weights be bolted to disks B and C to balance the system dynamically?
A flywheel of mass 950 kg rotates at a speed of 725 rev/min and has a radius of gyration of 135 mm. The flywheel is engaged by means of a clutch to a stationary shaft which has a mass of 1000 kg and a radius of gyration of 90 mm. Calculate the speed of the flywheel/clutch assembly after engagement.

The internal and external radii are 125 mm and 200 mm. Take friction coefficient as 0.3 and the spring force as 600 N. Assume that only one side of clutch is effective.
Hey, please reply as soon as POSIBLE! Wheel A, of 30kg, is located in the position shown by the effect of idler wheel D (frictionless wheel) and the system rope-spring BC. The static coefficient of friction is 0.50 and the kinetic coefficient is 0.40 between all the contact surfaces. If the force exerted by the horizontal spring is 60 N: a) Determine whether or not wheel A is turning when a moment M of 60 Nm is applied at point G. b) If it is shown that under the previous condition the wheel is turning, calculate the new value of the moment M necessary for the wheel to keep turning in equilibrium. Also indicate the frictional force that is generated at point F under that condition.
The 2.00-kg slender rod shown is hanging in a vertical position and is pin-supported at point A. The slender rod is initially at rest until a 1.000-kg block C, strikes it at its end at point B.The block slides on a frictionless surface with a velocity of 3.50 m/s to the right. After the impact, it slides with a velocity of 1.250 m/s to the right, and the bar rotates with an angular velocity, ω'. 1. What gives the correct kinematic relationship relating the final velocity of the center of the rod, v' , and its angular velocity, ω'? 2.

A Proell governor has arms of 300 mm length. The upper arms are hinged on the axis of rotation, whereas the lower arms are pivoted at a distance of 35 mm from the axis of rotation. The extension of lower arms to which the balls are attached are 100 mm long. The mass of each ball is 8 kg and the mass on the sleeve is 60 kg. At the minimum radius of rotation of 200 mm, the extensions are parallel to the governor axis. Determine the equilibrium speed of the governor for the given configuration. What will be the equilibrium speed for the maximum radius of 250 mm?

In your job as a mechanical engineer you are designing aflywheel and clutch-plate system. DiskA is made of a lighter material than disk B, and the moment of inertia ofdisk A about the shaft is one-third that of disk B. The moment ofinertia of the shaft is negligible. With the clutch disconnected, A isbrought up to an angular speed v0; B is initially at rest. The acceleratingtorque is then removed from A, and A is coupled to B. (Ignorebearing friction.) The design specifications allow for a maximum of2400 J of thermal energy to be developed when the connection ismade. What can be the maximum value of the original kinetic energyof disk A so as not to exceedthe maximum allowed value of the thermalenergy?
If either a simple or a compound pendulum is used to determine experimentally the acceleration of gravity g, difficulties are encountered. In the case of the simple pendulum, the string is not truly weightless, while in the case of the compound pendulum, the exact location of the mass center is difficult to establish. In the case of a compound pendulum, the difficulty can be eliminated by using a reversible, or Kater, pendulum. Two knife edges A and B are placed so that they are obviously not at the same distance from the mass center G, and the distance l is measured with great precision. The position of a counterweight D is then adjusted so that the period of oscillation τ obtained is equal to that of a true simple pendulum of length l and that g 4π2 l/τ.
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. The mechanism shows two identical 2-kg bars that are 0.15 m long each. They are hinged together at the lower ends and are supported at the upper ends by small rollers of negligible mass which roll on a horizontal rail. Determine the steady state angle θ assumed by the bars when they are accelerating under the action of a constant horizontal force 375.90 Newtons. Also, find the forces on the rollers at A and B as well as the reactions at the hinge C.

Question 2 The speed of the pickup truck’s engine is controlled by the Porter governor with 4 arms of equal length, and pivot on the axis of rotation. Each ball has a mass of 4 kg and the mass of the central load on the sleeve is 20 kg. The radius of rotation of the ball is 150 mm when the governor begins to lift, and 200 mm when the governor is at maximum speed. The initial angular speed of the engine’s crank is 14 rad/s, and it has reached a maximum speed at an acceleration of 0.4 rad/s2 after 5 seconds.2(a). If the speed of the crank of an engine is equal to the speed of its governor, calculate the angle between the upper arm and axis of rotation (?) when the governor starts to lift and when it is at maximum speed. 2(b). Prove that the length of the governor’s arms is equal.
