Question:

The piston (Figure 2) has fluid on both sides. The gage pressure below the piston P1 = 25 kPa and the absolute pressure above the piston P2 = 80 kPa . What force F must be applied to the piston to keep it stationary? The diameter D = 10 cm . Neglect the magnitude of the force due to Patm acting on the rod relative to the magnitude of the force due to P2 acting on the piston.

F= N

A 1 kg object is attached to a spring and stretches it 0.2 m on its own. There is no damping in the system, but an external force is present, described by the function F(t) = 6 cos omega t. The object is initially displaced 30 cm downward from equilibrium with no initial velocity and system experien...
