Web4. Integrate along the axis using the relevant bounds. A couple of hints for this particular problem: 1. You know the cross-section is perpendicular to the x-axis. A width dx, then, should given you a cross-section with volume, and you can integrate dx and still be able to compute the area for the cross-section. WebThe formula for the terminal velocity of a falling object (V t) can be calculated from the body's mass m, the density of the fluid in question (p, in kg/m 3, e.g. 1.225 for air), the cross-sectional area projected by the … WebThe table below can be used to convert American Wire Gauge (AWG) to square mm cross sectional area.
