Although different in many respects‚ liquids and gases have a common characteristic in which they differ from solids; they are fluids‚ lacking the ability of solids to offer permanent resistance to a deforming force. Fluids flow under the

Emily Chuang Mechanics of Swimming The crawl‚ also known as freestyle‚ is often regarded as the fastest swimming style. The legs perform a fluttering movement called the flutter kick to propel the body from behind while the elbows take turns moving in a semicircle movement in the swimming direction. One arm relaxes while the other is driven forward. The head is to be kept down in the water when not breathing. To breathe‚ the head turns sideways out of the water and air is to be taken in by the mouth

02TTB204 Mechanics of Solids Part B Lab Buckling of Struts 1. Introduction The task was given to obtain the buckling stresses for pin-ended steel struts of various slenderness ratios and compare with theoretical predictions obtained using the Euler and Rankine-Gordon equations. 2. Theory The method of obtaining the buckling stresses followed was to use data show in Appendix A. From the record of applied load‚ P‚ against deflection‚ δ‚ a Southwell plot of δ against

Celestial Mechanics Orbital Maneuvers Earth‚ Moon‚ Mars‚ and Beyond Rodolfo G. Ngilangil Jr. MBA‚ BSAE Impulsive Maneuvers Impulsive maneuvers are those in which brief firings of onboard rocket motors change the magnitude and direction of the velocity vector instantaneously. The position of the spacecraft is considered to be fixed during the maneuvers. This is true for high-thrust rockets with burn times short compared with the coasting of the spacecraft.
