Practice Questions
Question 1
In deriving the flexure formula for beams ($\sigma = \tfrac{My}{I}$), which key assumption is made?
Question 2
Which relationship correctly defines true strain $\varepsilon_t$ in terms of engineering strain $\varepsilon$?
Question 3
A pinned–pinned steel column has length $L=2.00\ \mathrm{m}$, flexural rigidity $EI=210\times10^9\ \mathrm{Pa}\times8.50\times10^{-6}\ \mathrm{m^4}$. What is its Euler critical buckling load $P_{cr}$?
Question 4
A simply supported beam with rectangular cross-section $b=50\ \mathrm{mm},\,h=100\ \mathrm{mm}$ carries a shear force $V=12\ \mathrm{kN}$. What is the maximum shear stress $\tau_{max}$?
Question 5
A circular shaft of diameter $d=50\ \mathrm{mm}$ is subjected to bending moment $M=1000\ \mathrm{N\cdot m}$ and torque $T=500\ \mathrm{N\cdot m}$. What is the von Mises equivalent stress $\sigma_e$?
