A chord is a straight line inside a circle that spans its circumference and the diameter of a circle is its largest chord.
Yes, a cord that is a diameter always passes through the center of a circle. And it's also the longest cord of that circle.
The recommended prusik cord diameter for climbing applications is typically between 6mm and 8mm.
The diameter
A diameter of a circle must pass through the center of that circle. A cord is a line segment that has its endpoints on the circumference of a circle. It can be any line segment. If that cord also passes through the center of the circle, it is said to be a diameter of that circle. A diameter of a circle is the longest cord of the circle.
The cord of a circle that contains the center of that circle is a diameter of that circle.
Diameter
Not sure if it's 100% true, but when I was PAT testing at work it said that a cord had a diameter of >4mm and a cable had a diameter of <4.mm
Diameter, cord, radious.
A cord that passes through the center of a circle is a diameter of that circle. And you've probably guessed that this is the largest cord of that circle.
They are not the same. Diameter is twice the size as radius.
The recommended cord diameter really depends on the type of machine you're using. Electric string trimmers are usually limited to 2.5mm maximum diameter, while gas trimmers can handle 2.75mm or even metal blade attachments.
s the equator and the diameter the same thing?
