an 8kg flywheel of radius r is
initially at rest. assume the radius of the gyration kG= 0.12m and
the radius of the flywheel r = 0.125m. an object B also of mass 8
kg is attached to a cord that is wrapped around a periphery of the
flywheel. the fly wheel starts to rotate clockwise with angular
velocity. the rotation is resisted by a constant frictional torque
mf in the bearing 1Nm. use the work energy principle to determine...

Please help with centroidal radius of gyration!
An automobile wheel-and-tire assembly with a total weight 47 lbs is attached to a mounting plate of negligible weight which is suspended from a steel wire. The torsional spring constant of the wire is known to be K = 0.40 lb-in./rad. The wheel is rotated through 90° about the vertical and then released. Knowing that the period of oscillation is observed to be 66 s, determine the centroidal mass moment of Inertia and...
A wheel-axle assembly is attached to a spring as shown in the figure below. The wheel-axel assembly has a mass of m=3 kg and a radius of gyration about the polar axis of kG=75mm. The spring has a stiffness of k=0.5 kN/m ( Note the units!). The system is released from rest with a spring extension of x1=0.2 m. Calculate the maximum angular velocity. Assume friction can be ignored. Provide your answers in rad/s.
Due Thu 06/06/2019 2:5 A force of 20 lb stretches a spring 2 ft. A 8-lb weight is attached to the spring and the system is immersed in a medium that imparts a damping force equal to its instantaneous velocity. (a) Find the equation of motion if the weight is released from rest 18 inches above equilibrium position. z(t) Preview (b) the weight is released 18 inches above the equilibrium position with an upward velocity of 3 ft/s. r(t) Preview...
the
100 lb spool A is held by a cable on its inner radius and the 70 lb
block B is attached to the spool by another cable on the outer
radius of the spool as shown. the spool has a radius of gyration of
k=4.0 in. if the system is released from rest, determine the
acceleration of the block B and the acceleration of the spool
immediatly afterbeing released.
