WebSuppose we could somehow load a prismatic bar by applying uniform normal stresses σ to its ends (Fig. 3.1 ). For this loading, it can be shown that the stress distribution on every plane perpendicular to the axis of the bar consists of the same uniform normal stress and no shear stress (Fig. 3.2 ). WebApr 1, 2024 · Figure shows a uniform iron bar B of weight $30N$ and length $1.40m$. The bar is being used to lift one edge of a concrete slab S. A stone, placed $0.20m$ from one end of B, acts as a pivot. A force of …
