Mean Diameter Formula

Introduction to mean diameter formula:

In mathematics, mean diameter is mainly used for the defining the shape of the circle. The other name given for the mean diameter is known as neutral axis. There are two terms present in the mean diameter. Two terms are called as the inside diameter and the thickness. In this article, we are going to study about mean diameter in detail with some examples problems.

Explanation to Mean Diameter Formula

The explanation to mean diameter formula is given below the following section,

Formula:

1)Mean Diameter:

Mean Diameter = Inside Diameter + Thickness

2)Another Mean Diameter:

Mean Diameter = Outside Diameter - Thickness

3)Mean circumference:

Mean Circumference  = Mean Diameter `xx` `Pi`

Example Problems to Mean Diameter Formula

Problem 1: Find mean diameter for the cylinder, where thickness is 25mm, inside diameter is 650mm.

Solution:

Step 1: Given:

Thickness is 25mm

Inside diameter is 650mm

Step 2:To Find:

Mean Diameter

Step 3: Formula:

Mean Diameter = Inside Diameter + Thickness

Step 4: Solve:

Mean Diameter = Inside Diameter + Thickness

MD = 650 + 25

= 675

Result: Mean Diameter = 675mm.

Problem 2: Find mean diameter for the cylinder, where thickness is 25mm, outside diameter is 650mm.

Solution:

Step 1: Given:

Thickness is 25mm

Outside diameter is 650mm

Step 2:To Find:

Mean Diameter

Step 3: Formula:

Mean Diameter = Outside Diameter - Thickness

Step 4: Solve:

Mean Diameter = Outside Diameter - Thickness

MD = 650 - 25

= 625

Result: Mean Diameter = 625mm.

Problem 3: Find mean circumference for the cylinder, where thickness is 25mm, outside diameter is 650mm.

Solution:

Step 1: Given:

Thickness is 25mm

Outside diameter is 650mm

Step 2:To Find:

Mean Circumference

Step 3: Formula:

Mean Circumference  = Mean Diameter  `xx`

Step 4: Solve:

Mean Circumference  = Mean Diameter  `xx`

Mean Diameter = Outside Diameter - Thickness

MD = 650 - 25

= 625

Mean Circumference  = Mean Diameter  `xx`

MC = 625  `xx`  3.14

= 1962.5

Result: Mean Circumference  = 1962.5mm
