In this system, there are two mass elements: m₁ and m₂. They are con- nected by a spring. m₁ is also connected to a massless rod, which can rotate at its midpoint. The other end of this massless rod is connected to another massless rod, which is connected to the ground through a spring and a damper. This configuration forms the basis of the system. You may assume small deflections for this problem and that the vertical connections are rigid links. When the coordinates y₁, y2, y are equal to zero, the gravi- tational force on the masses is covered by springs (the system is at its static deflection). Two input forces, fi and f2, are applied on the masses m₁ and m2 respectively. HINT: You should not consider the gravity force in your solution.

Their absences will automatically make the problem false. F The 77-kg man pushes on the 120-kg crate with a horizontal force F. The coefficient of static friction between the man's shoes and the surface is 0.82.

When the rod is perfectly horizontal, the angle 0 = 0, the displacement y 0, and the springs are in neither tension nor compression. Gravity acts on the system (e.g. on mass M).

1. A foot pedal mechanism can be roughly modeled as a simple pendulum connected to a spring modeled as a pendulum connected to spring as depicted below. The purpose of the spring is to provide a return force for the pedal action. Compute the spring stiffness needed to keep the pendulum at 1° from the horizontal line and then obtain the natural frequency. Assume that that the angular deflections are small. Note that the pedal is horizontal when the spring is at its free length. The values in the figure are m = 0.5 kg, g = 9.8m/s², l₁ 0.2 m, and 12 = 0.3 m. 4₁ www 12 k 0 m 8
