Question

Consider the solid bar with axial loading along its length as shown above, the cross sectional area of the bar is A=5in^2, E=30x10^6 PSI

(a) Determine the axial force in each section and designate if each section is in tension or compression

(b)determine the largest tensile stress and the largest compressive stress

(c) Determine the deflection of point "D" relative to the rigid wall at "A"

Consider the solid bar with axial loading among its length as shown below, the cross-section area of the bar is A = 51n2, Determine the axial force in each section and designate if each section is in the tension or compression Determine the largest tension stress and the largest compressive stress Determine the deflection of point "D" Relative to the rigid wall at "A"

Explanation / Answer

(a) AB = tensile; compressive; CD=tensile; DE=compressive; EF=tensile

(b) EF = 50k/(5*6) largest tensile; BC = 150k/(5 in^2 * 6 ft) = largest compressive

Convert to appropriate units. I am not comfortable dealing with imperial system.

(c) At D, Stress = 30k/(5)

So, E=Stress/Strain

So, Deflection = 12 ft * Stress/E
