QUESTION:
An axial load P is applied to the 32-mm-square aluminum bar BC as shown. When P = 24 kN, the horizontal deflection at end C is 4 mm. Using E = 70 GPa, determine
(a) the eccentricity e of the load
(b) the maximum stress in the bar
ANSWER:
Step 1 of 3
Given data:
The side of a square aluminum bar is given as, \(b = h = 32\;{\rm{mm}} = 32 \times {10^{ - 3}}\;{\rm{m}}\).
Horizontal deflection is given as, \({y_{\max }} = 4\;{\rm{mm}} = 4 \times {10^{ - 3}}\;{\rm{m}}\).
Young's modulus is given as, \(E = 70\;{\rm{GPa}}\).
Allowable load is given as, \(P = 24\;{\rm{kN}}\)
The length is given as, \(L = 0.65\;{\rm{m}}\).
Step 2 of 3
(a)
Horizontal deflection can be determined as,
\({y_{\max }} = e\left( {\sec \left( {\frac{\pi }{2}\sqrt {\frac{{{{\left( {2L} \right)}^2}P}}{{{\pi ^2}E\left( {\frac{{b{h^3}}}{{12}}} \right)}}} } \right) - 1} \right) \)
Here, e is the eccentricity.
Substitute the values in the above formu
