Short Answer

Athletes such as swimmers and bicyclists wear body suits in competition. Formulate a list of pros and cons of such suits.

Pros- Bicyclists use bodysuits that fit like a second skin to reduce exposed areas. Because it hugs the body, it reduces wind resistance and gives them more freedom of movement.

Cons- A damp swimsuit can irritate the skin, causing damage to the hair follicles and increasing the risk of infection, particularly from germs.

Step by Step Solution

Definition of Athletes

Athletes compete in sports that need physical strength, speed, or endurance.

Formulating list of pros of suits

To counter the drag force due by water and air swimmers and bicyclists wear bodysuits in competition.

Swimmers and cyclists wear different types of bodysuits. Because they are made to work in a variety of media.

The formula for calculating air drag is as follows:

FD = 12CpAv2

Where C represents the drag coefficient, A represents the item's surface area in contact with the fluid and p is the fluid density.

Air drag is therefore proportional to the square of the velocity and exposed area.

A skin-tight cycling skin suit that hugs the cyclist's body. Normal apparel, such as jeans or jogging outfits, is more prone to "catch" the wind, increasing the exposed area and causing the rider to slow down. Because a cycling skinsuit has no loose regions, the cyclist can move forward while ignoring the issue of wind resistance on the cyclist's body.

In order for a cyclist to ride quicker, their clothing should not catch the wind.

Bicyclists use bodysuits that fit like second skin to reduce exposed areas. Because it hugs the body, it reduces wind resistance and gives them more freedom of movement.

These suits can be unpleasant and cause skin irritation for certain cyclists.

Formulating list of cons of suits

If the thing is really small, moving slowly, or in a denser medium than air, on the other hand. As a result, the drag force is proportional to the velocity alone. This relationship exists, according to Stokes' law.

Fs= 6πηrv

Where r is the object's radius, v is the object's velocity, and η is the fluid's viscosity.

To decrease drag forces, fish, dolphins, and even huge whales have streamlined shapes.

Swimmers also use swimsuits to streamline their bodies and reduce drag. A swimsuit is necessary to preserve body heat and protect the body core from hypothermia. It safeguards swimmers against waterborne illness and toxins present in the water.

A damp swimsuit can irritate the skin, causing damage to the hair follicles and increasing the risk of infection, particularly from germs.
