Description

If the speed of the driven pulley is known, and the problem is to find its diameter or the value of d instead of s, this formula can be rearranged or changed.

When the values are thus inserted, in place of the letters, the result or answer is obtained by ordinary arithmetical methods.A discussion of techniques available for calculating the coordinates of hole circles begins on Handbook page 708, and tables of calculated hole circle coordinates are given starting on page 712. Example 3: Find the area of a segment of a circle, the center angle of which is 57 degrees, and the radius 2½ inches. If machine steel has a tensile strength of 55,000 psi, what should be the diameter of a rod to support 36,000 pounds if the safe working stress is assumed to be one-fifth of the tensile strength? A chord of a circle is the distance along a straight line from one point to any other point on the circumference.

By following practical techniques explained in the Guide and cross-referenced to the Handbook, readers will enhance their ability to reach specific information and solutions more quickly and easily.

To illustrate by a simple example, the formula for determining the speed ( s) of a driven pulley, when its diameter ( d) and the diameter ( D) and speed ( S) of the driving pulley are known, is as follows: s = ( S × D) / d.
