4. Stress in a Bar of Uniformly Tapering Rectangular Cross Section Let, b1 and b2 = Width of the larger and smaller end of the bar respectively L and t = Length and thickness of the bar respectively b 2 b 1 P P t x dx

5. Stress in a Bar of Uniformly Tapering Rectangular Cross Section Let, b1 and b2 = Width of the larger and smaller end of the bar respectively L and t = Length and thickness of the bar respectively E = Modulus of elasticity or Young’s modulus of the material b 2 b 1 P P t x dx

6. Stress in a Bar of Uniformly Tapering Rectangular Cross Section The cross sectional area of the element, Ax = Width × Thickness = (b1 – kx ) × t Tensile stress induced in the small element  = P / A Total elongation or extension of the element length

7. Example A steel flat plate of 20 mm thickness, uniformly tapers from 200 mm to 100 mm width in the a length of 500 mm. Find the extension of the plate if an axial pull of 40 kN is applied at its ends.
