2. In order for an airplane to remain in level, steady flight, what must happen to the four forces?
3. Describe the relationship between the total lift, vertical component of lift and weight during the following maneuvers:
Aircraft banks at a constant altitude
After take-off, the aircraft executes a climbing turn
Aircraft is in a descending turn to align with the runway
4. If the mass remains constant and the force changes, what happens to the acceleration of an object?
5. If the force remains constant and the mass changes, what happens to the acceleration of that object?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
