Problem $7\mathrm{.}4-5$

Pts : $29$

An element on the top surface of the fuel tanker in Problem $7\mathrm{.}2-1$ is in biaxial stress

and is subjected to stresses

${}_x=6250,{}_y=-1750$

as shown in the figure.

Using Mohr's circle, determine the following:

$($a$)$ The stresses acting on an element oriented at a counterclockwise angle $=55$ from the x axis.

B$.$ sketch trh result on a properly oriented element

C$.$ The maximum shesr stressed and associated normal stresses

D$.$ Show the results on sketched of properly oritnted elements
