The chain drive of the bicycle changes the input pedalling force and pedalling speed into an output. … A system diagram shows how a system will change inputs into outputs. The process changes the inputs into outputs. When you change the pedalling force or the pedalling speed on a bicycle, the output speed will change.
How is a bicycle a system?
Yes we think of a bicycle as a system because a bicycle is made of many subsystems, and each subsystem has its own job. For example, brakes slow down the bike and the wheels move the bike. … When all the subsystems are working together, it creates a working bicycle.

What is the input and output of a bike?
The input is what you put into a bicycle when you ride it. It is the pedalling force and the pedalling speed. In the process box in the middle is the bicycle. The chain drive of the bicycle changes the input pedalling force and pedalling speed into an output.

What is a bicycle seat stay?
The seat stays connect the top of the seat tube (often at or near the same point as the top tube) to the rear fork dropouts. A traditional frame uses a simple set of paralleled tubes connected by a bridge above the rear wheel.
What force is used to ride a bicycle?
Static friction is also the force that is most effective in stopping the bicycle. In a normal stop—one that does not involve any skidding of the tires—it is the force of static friction between the ground and the tires that causes the deceleration of the bicycle.
|Ice on ice||0.05–0.15 ||0.02 |
What makes a bike fast?
Real racing bikes are fast because they use supple high-performance tires. Their frames flex just the right amount for a powerful rider. Racing bikes are fast because the rider has little wind resistance thanks to the low riding position, narrow handlebars, and tight-fitting clothing.
What is a bicycle exercise?
