17.74 The 60-lb uniform disk A and the bar BC are at rest and the 10-lb uniform disk D has an initial angular velocity, of magnitude 440 rpm when the compressed spring is released and disk D contacts disk A. The sys- tem rotates freely about the vertical spindle BE. After a period of slippage. disk D rolls without slipping. Knowing that the magnitude of the final angu- lar velocity of disk D is 176 rpm, determine the final angular velocities of bar BC and disk A. Neglect the mass of bar BC.

A uniform 144-lb cube is attached to a uniform 136-lb circular shaft as shown, and a couple M with a constant magnitude is applied to the shaft when the system is at rest. Knowing that r = 4 in., L= 12 in., and the angular velocity of the system is 960 rpm after 4 s, determine the magnitude of the couple M.
Dynamic Problem, reply as soon as posible. The double pulley system weighs 30 lbs. and has a 6.5-inch center radius of gyration. Cylinders A and B areconnected to the double pulley by cords that wrap around the circles whose radii are shown. Thecoefficient of kinetic friction between block B and the surface is 0.25. If the system is released from rest atposition shown, determine:A) The velocity of cylinder A just before hitting the ground.B) The total distance cylinder B travels before coming to rest.
Can you explain the radius of gyration ? why is it 480mm for the rod & 120mm for the disk. How do we figure this out ? thank you

A 197-kg flywheel is at rest when a constant 300 N·m couple is applied. After executing 560 revolutions, the flywheel reaches its rated speed of 2400 rpm. Knowing that the radius of gyration of the flywheel is 400 mm, determine the average magnitude of the couple due to kinetic friction in the bearing. N.m. The average magnitude of the couple due to kinetic friction in the bearing is [
A stationary horizontal plate is attached to the ceiling by means ofa fixed vertical tube. A wheel of radius aa and mass mm is mounted on a light axle ACAC that is attached by means of a clevis at AA to a rod ABAB fitted inside the vertical tube. The rod ABAB is made to rotate with a constant angular velocity ΩΩ causing the wheel to roll on the lower face of the stationary plate. Determine the minimum angular velocity ΩΩ for which contact is maintained between the wheel and the plate. Consider the particular cases ( aa ) when the mass of the wheel is concentrated in the rim, (b) when the wheel is equivalent to a thin disk of radius aa also extend the problem using Kinematic and Kinetic analysis

A Hartnell type spring loaded governor rotates about a vertical axis. The two rotating masses weigh 10 N each rotate at a radius of 130 mm when the speed is 600 r.p.m. At this speed the arms, which are vertical and horizontal, have effective lengths of 110 mm and 80 mm respectively. The equilibrium sped is 630 r.p.m when the rotating masses are at their maximum radius of 160 mm. Determine the stiffness rate of spring, the compression of spring at 600 r.p.m.
Problem 2: The mechanism shown is one of two identical mechanisms attached to the two sides of a 90-kg. uniform rectangular door. Edge ABC of the door is guided by wheels of negligible mass that roll in horizontal and vertical tracks. A spring of constant k 600 N/m is attached to wheel B. Knowing that the door is released from rest in the position 6 30° with the spring unstretched, determine the velocity of wheel A just as the door reaches the vertical position,
The rotor of an electric motor has an angular velocity of 3600 rpm when the load and power are cut off. The 120-lb rotor, which has a centroidal radius of gyration of 9 in., then coasts to rest.
