Derive the equation of motion for the following system, using (the rotation of the beam about the hinge) as the degree-of-freedom. Not that there is an applied force (Fo sin wt) as well as an applied moment (Mo sin wt). The total bar mass is m. Treat the bar as two bars: one to the left of the hinge point; one to the right. The one to the left has a mass moment of inertia of- mL²; the one to the right has a mass moment of inertia of- mL². Then transform this differential equation of the Laplace domain, assuming zero initial 27 192 1 192 conditions. Lastly, compute the damping ratio and damped natural frequency for this system.

With the elbow flexed 30 degrees, the moment arm of the biceps is equal to 10 mm. Solve for the force exerted by the biceps given the following assumptions: ​—the biceps is the only muscle active ​—the center of mass of the forearm is located 200 mm from the elbow center of rotation ​—the mass of the forearm is 2 kg

The figure below shows the positions of the Centers of mass of the three disks on a rotating shaft. m. =6 kg, M2=4 kg, m3=5 kg, r-=100 mm, r2=200 ver3 = 300. B to dynamically balance the shaft it is desirable to place balancing masses of 3 kg each in their planes. Balancing find the positions of the center of mass (004) of mass A in the unit of cm and degrees. The D value in the figure is 200 mm. mlg my m1 37 53 200 mm 150mm 200 mm ma Please choose one n
