Given: A shaft rotates about a fixed vertical axis at a constant rate of f, as shown below. A straight bar OA, having a length of L, is pinned to point O on the shaft, with O being on the rotation axis of the shaft. At the instant when 0-0, bar OA is being raised at a rate of 0 from the horizontal plane, with this rate changing at a rate of 6. A set of ryz coordinate axes is attached to bar OA with its origin at O. A second set of coordinate axes, XYZ, are fixed to ground. At the instant when 0", the zyz and XYZ axes are aligned with each other. Find: For the instant when -0°, determine the angular velocity and angular acceleration of bar OA. vertical shaft bearing 0 X bar Use the following parameters in your analysis: 2-5 rad/s, 4 rad/s, -3 rad/s² and L=2 m.

In the mechanism in Figure-1, we use the virtual powers method for the values given in the table below.Calculate the moment M using Use ω (rad/s) ⟲ of rod AB to find the required velocities.Assume it rotates at speed. theta= 25 degree R1=300N R2=200N L=1,3m k=500N/m
