Cantilever Beam Displacement Formula Design Talk Example cantilever beam with single load at the end, metric units. the maximum moment at the fixed end of a ub 305 x 127 x 42 beam steel flange cantilever beam 5000 mm long, with moment of inertia 8196 cm 4 (81960000 mm 4), modulus of elasticity 200 gpa (200000 n mm 2) and with a single load 3000 n at the end can be calculated as. m max. The general formulas for beam deflection are pl³ (3ei) for cantilever beams, and 5wl⁴ (384ei) for simply supported beams, where p is point load, l is beam length, e represents the modulus of elasticity, and i refers to the moment of inertia. however, many other deflection formulas allow users to measure different types of beams and deflection.
Cantilever Beam Deflection Calculation Example Design Talk Where: \ (m x \) = bending moment at point x \ (p \) = load applied at the end of the cantilever \ (x \) = distance from the fixed end (support point) to point of interest along the length of the beam. for a distributed load, the equation would change to: \ (m x = – ∫wx\) over the length (x1 to x2) where: w = distributed load x1 and x2 are. The tables below give equations for the deflection, slope, shear, and moment along straight beams for different end conditions and loadings. you can find comprehensive tables in references such as gere, lindeburg, and shigley. however, the tables below cover most of the common cases. for information on beam deflection, see our reference on. 2. cantilever beam – concentrated load p at any point 2 pa 2 e i lei 2 3for0 px yax xa 6 ei 2 3for pa yxaaxl 6 ei 2 3 pa 6 la ei 3. cantilever beam – uniformly distributed load (n m) 3 6 l e i 2 22 64 x yxllx ei 4 max 8 l e 4. cantilever beam – uniformly varying load: maximum intensity o 3 o 24 l e i 2 32 23 o 10 10 5 120 x yllxlxx 4 o.
