The
two springs, each of stiffness k = 1.20 kN/m, are of equal length
and undeformed when θ = 0. If the mechanism is released from rest
in the position θ = 32°, determine its angular velocity θ˙ when θ =
0. The mass m of each sphere is 2.6 kg. Treat the spheres as
particles and neglect the masses of the light rods and springs.

The torsional spring at A has a stiffness = 25 N.m/rad and is undeformed when the uniform 20-kg bars OA and AB are in the vertical position and overlap. If the system is released from rest with 0 = 67°, determine the magnitude of the angular velocity of wheel B when 0 = 25º. The 13-kg wheel at B has a centroidal radius of gyration of 50 mm and is observed to roll without slipping on the horizontal surface. kr...

Two equal length springs having a stiffness of : K A = 300 N/m KB = 200 N/m Are nested together in order to form a shock absorber. If a two kilogram block is dropped from an at rest position 0.6 meters above the springs, what is the deformation of the springs when the block momentarily stops at the bottom of its path of travel ?

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.
