How do biomechanical understandings influence the learning of and performance in surfing? Problem: The problem with my surfing is my paddling technique. Understanding the fundamental relationships in mechanics‚ helps form a foundation for the analysis of human movement in surfing. The main principle or law of motion I am going to look into is Newton’s Law of Action and Reaction. This law of motion is mainly applied when paddling. It helps me understand how the application of force to my arm

exploited by hummingbirds during hovering should be similar to those observed in insects. To test these predictions‚ we flew rufous hummingbirds (Selasphorus rufus‚ 3.3 g‚ n = 6) in a variable–speed wind tunnel (0-12 ms-1) and measured wake structure and dynamics using digital particle image velocimetry (DPIV). Unlike hovering insects‚ hummingbirds produced 75% of their weight support during downstroke and only 25% during upstroke‚ an asymmetry due to the inversion of their cambered wings during upstroke

MEHB221 Fluids Mechanics Lab 2014 Experiment No. 5 HEAD LOSS DUE TO PIPE FRICTION Objective To verify that Darcy-Weisbach equation can be used to predict the head loss due to friction with flow of water through a smooth bore pipe. Apparatus Fluid Friction Apparatus‚ FM100. Hydraulic Bench‚ FM110. Summary of theory For water flowing through a circular pipe‚ the head loss due to the friction can be calculated using Darcy-Weisbach equation. h = 4fLu2 2gd Or h = λLu2 2gd Where L = length of pipe

applications. In this review we examine results from simulations of both attached and separated flows on coarse grids in which the near-wall regions are not resolved and are instead represented by approximate wall boundary conditions. The simulations use the dynamic Smagorinsky subgrid-scale model and a second-order finite-difference method. Typical results are found to be mixed‚ with acceptable results found in many cases in the core of the flow far from the walls‚ provided there is adequate numerical resolution
