Comparison between the simulation results of angular speed, load torque and current obtained from the model

how to calculate a cross-sectional area | sciencing

Feb 07, 2020 · To calculate the cross-sectional area of a plane through a three-dimensional solid, you need to know the precise geometry of the solid and the angle the cutting plane makes with the solid's axis of symmetry, if any. The area of cross-sections have unique formulas depending on the solid

relation between iliopsoas cross-sectional area and kicked

This study aimed to investigate the relationship between the maximal anatomical cross-sectional area (ACSA) of the iliopsoas muscle and ball speed in side-foot and instep kicks. The ACSA of the psoas major and iliacus was measured in 29 male collegiate soccer players by using magnetic resonance imag …

ca2385068a1 - golf ball dimples with curvature continuity

A golf ball (20) having a surface (22) thereon with a plurality of dimples (34, 36, 38, 40, 42, 44 and 46) on the surface (22) is disclosed herein. The contour (199) of each of the dimples (34, 36, 38, 40, 42, 44 and 46) is continuous from a first edge (200a) of each of the dimples (34, 36, 38, 40, 42, 44 and 46) to a second opposing edge (200b) of each of the dimples (34, 36, 38, 40, 42, 44

valves 101: two types of ball valves - crossco

A floating design ball valve sandwiches the hollow ball between two or more cupped seats that form a tight seal between the body and the ball at the inlet and outlet ports of the valve body. The ball is rotated (usually 90 degrees) by a shaft that protrudes outside of the valve body and is connected to some form of operator. For this reason, most ball valves are referred to as quarter-turn valves

7.1: strength of human bones - physics libretexts

Sep 09, 2020 · We divide the compressive force by the cross-sectional area to find the compressive stress on the bone. Our approximate value for the ultimate strength of bone that would be required to support 30x body weight was 80 MPa , which is actually less than the measured value of 205 MPa , so the claim that the femur can support 30x body weight seems

an intense stream of water of cross section area a strikes

A horizontal pipe line carries water in a streamline flow. At a point along the pipe where cross sectional area is 1 0 c m 2, the water velocity is 1 m s − 1 and the pressure is 2 0 0 0 P a. The pressure of water at another point where the cross sectional area is 5 c m 2 is

drag on a soccer ball

May 05, 2015 · where D is the drag, A is the cross-sectional area, and cd is the drag coefficient a number that represents all of the complex factors affecting drag. Drag coefficients for a specific object are determined experimentally using a model in a wind tunnel. For flow past a ball, determining the drag coefficient gets a little more confusing
