Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.

(A) Maximum principal stress theory:-The
theory states that the failure of the
mechanical component subjected to bi-
axial or tri-axial stresses occurs when the
maximum principal stress reaches the yield
or ultimate strength of the material.
if o1,02,03 are the three principal stresses
at a point on the component
and oj > 02 > 03 then according to this
theory, the failure occurs whenever,

(B) Maximum shear stress theory:- The
theory states that the failure of a
mechanical component subjected to bi-
axial or tri-axial stresses occurs when the
maximum shear stress at any point in the
component becomes equal to the
maximum shear stress in the standard
specimen of the tension test when yielding
starts.If o1, 02 ,03 three principal stresses

Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…
