MACHINE SHOP CALCULATION - OD1640 - LESSON 2/TASK 3
Find the largest square which may be cut from a 13 cm diameter bar of round
Largest square = diameter of stock x .707
= 13 cm x .707
= 9.191 cm
Find the diameter of round stock required to cut a square of 10 cm.
General Procedure for Solving Problems in Trigonometry
It is relatively easy to solve a shop problem when the necessary right
triangle is immediately obvious.
But in actual practice, problems arise
which involve shapes other than right triangles.
In such cases, it is
necessary to resolve the problem into right triangles by means of connecting
lines. This procedure is called "triangulation". Sometimes as many as four
right triangles must be constructed in order to figure a desired value.
Where any difficulty is experienced in recognizing the elements of the
necessary right triangles, it is advisable to construct a diagram three or
four times larger than actual size, according to scale.
