Mechanics of Materials is a comprehensive engineering text that explores the fundamental behavior of materials under various loading conditions. The book introduces core principles such as stress, strain, and deformation, using both theoretical derivations and experimental methodologies to illustrate how materials respond under axial, bending, torsional, and shear forces. It further integrates practical design approaches—covering beams, shafts, and columns—through methods like energy analysis, stress transformation techniques, and buckling analysis to ensure safe and efficient structural performance. Overall, the text balances rigorous analytical concepts with application-oriented design principles, making it an essential resource for understanding and solving real-world engineering problems.

Problem 1
A $2014-$ T6 aluminum alloy column has a length of $6 \mathrm{m}$ and is fixed at one end and pinned at the other. If the cross-sectional area has the dimensions shown, determine the critical load. $\sigma_{Y}=250 \mathrm{MPa}$

Problem 3
A shaft is made of an aluminum alloy having an allowable shear stress of $\tau_{\text {allow }}=100$ MPa. If the diameter of the shaft is $100 \mathrm{mm}$, determine the maximum torque $\mathbf{T}$ that can be transmitted. What would be the maximum torque $\mathbf{T}^{\prime}$ if a 75 -mm-diameter hole were bored through the shaft? Sketch the shear-stress distribution along a radial line in each case.

Problem 4
The force applied at the handle of the rigid lever causes the lever to rotate clockwise about the pin $B$ through an angle of $2^{\circ} .$ Determine the average normal strain in each wire. The wires are unstretched when the lever is in the horizontal position.
Problem 5
The A992 steel rod is subjected to the loading shown. If the cross-sectional area of the rod is $80 \mathrm{mm}^{2},$ determine the displacement of $B$ and $A .$ Neglect the size of the couplings at $B$ and $C$
Problem 6
An air-filled rubber ball has a diameter of 6 in. If the air pressure within the ball is increased until the diameter becomes 7 in., determine the average normal strain in the rubber.
