1. Euler's formula for a mild steel long column hinged at both ends is not valid for slenderness ratio
2. In a rectangular beam, when width, depth and length are doubled, the bending stress
3. If load at the free end of the cantilever beam is gradually increased, failure will occur
4. Slope and deflection at a point in a loaded cantilever beam carrying several loads can be found out by the
5. The principal stresses σ1, σ2 and σ3 at a point respectively are 80 MPa, 30 MPa and -40 MPa. The maximum shear stress is
6. The ratio of maximum shear stress to hoop stress in a thin cylindrical pressure vessel is
7. A steel beam of length 30 m is fixed between two supports at 8°C with no stress. Find the expansion allowances given if the stress in the bar is to be zero when temperature is raised to 50°C ( α= 12 ×10^-6 per °C, E = 2× 10^5 N/mm^2)
