A mechanic uses a crowfoot wrench to loosen a bolt at E. Knowing that the mechanic applies a vertical 24-lb force at A, determine using Mohr's circle method the principal stresses and the maximum shearing stress at point H located as shown as on top of the 3/4-in. diameter shaft (this is the problem of 7.47 in the 7th edition).

Sagot :

As a result, the diameter of the shaft, as determined by Mohr's circle method, is 3.4 ksi.

What is Mohr's circle method?

The transformation equation for issues involving plane stress are shown graphically by Mohr's circle. It helps to visualize the relationship between normal and shear loads acting on a stress component at any required direction. This process was developed by a German scientist by the name of Karl Friedrich Mohr. As a result, this procedure was given the moniker Mohr's method. Direct titration is a part of the procedure. Chloride ion solution serves as the analyte in this process, while silver nitrate is utilized to prepare titrants.

What is Mohr equation?

The major stress and maximum shear stresses are identified, along with their planes, using Mohr's circle, which also aids in visualizing the normal stress and shear stress acting on the plane. Maximum shear stress (max) equals (σ1-σ2). Mohr's Circle coordinate is represented by the symbols σx,σy. Mohr's Circle Center (C) = ((σ1+2)/2, 0)
