Bare skin is slicker than hairy skin, so shaving arms and legs will reduce air drag by a tiny amount for a cyclist.
Shaving one's legs does not actually reduce the aerodynamic resistance on one's body. It is, however, advantageous in the treatment of cuts and scrapes ("road rash"), reducing the amount of dirt stuck to one's legs, as well as keeping one's legs cooler then if they were hair covered. Mountain bikers may shave for said benefits as well as greatly reducing the chance of attracting ticks.
Regardless of quantifiable benefits, leg shaving has been shown to produce significant placebo effects, that is, a cyclist with shaved legs tends to perform better simply because he believes he has a significant advantage.
Shaving his head/wearing swim cap, shaving body/facial hair, wearing speedo.
This is very likely a reaction to shaving. Changing to a milder shaving soap, a better shaving system and thourough rinsing before and after will reduce this reaction. A skin conditioner applied after shaving will also help. Shaving in the direction of the hair not against it will reduce the damage to the surrounding skin.
To reduce drag, you can: Streamline the shape of the object to minimize resistance. Smoothen the surface to reduce friction. Eliminate unnecessary protrusions or features that contribute to drag.
no
don't drag it copy and paste it
it doesn't
To reduce drag, you can streamline the shape of the object, minimize surface roughness, and reduce the frontal area exposed to the flow of air or water. Additionally, reducing speed can also help decrease drag forces.
to reduce drag
A car will have aerodynamic features to reduce forces of friction and drag. A sleek body style will help do this.
Airplanes are designed to reduce drag by incorporating streamlined shapes and smooth surfaces to minimize air resistance. Winglets at the end of wings help reduce the formation of vortexes that create drag. Advanced materials and coatings are also used to reduce skin friction drag on the aircraft's surface.
using controller to control it.. decrease weight to reduce drag
to reduce drag you must make your shape more streamlined and more aerodynamic this meaning reducing drag so that there is less resistance therefore creating speed
