Maximum Slope and Deflection of Cantilever Beam
Given Data:
- Span of Cantilever Beam, L = 4m
- Uniformly Distributed Load, w = 5kN/m
- Flexural Rigidity, EI = 8x10^4 kN/m^2
Maximum Slope:
The maximum slope of the cantilever beam can be calculated using the following formula:
θmax = (wL^3)/(6EI)
Substituting the given values, we get:
θmax = (5x4^3)/(6x8x10^4) = 0.05 radians or 2.86 degrees
Maximum Deflection:
The maximum deflection of the cantilever beam can be calculated using the following formula:
ymax = (wL^4)/(8EI)
Substituting the given values, we get:
ymax = (5x4^4)/(8x8x10^4) = 0.05m or 50mm
Explanation:
A cantilever beam is a type of beam that is supported at only one end. The other end is free to move, and hence it is called the free end. When a uniformly distributed load is applied to the beam, it causes a bending moment to be developed along the length of the beam.
The maximum slope and deflection of the cantilever beam occur at the free end. The slope is the angle between the tangent to the deflected shape of the beam and the horizontal axis. The deflection is the distance between the original position of the free end and its deflected position.
The flexural rigidity of the beam is a measure of its resistance to bending. It depends on the material properties, cross-sectional geometry, and length of the beam. The higher the flexural rigidity, the lower the slope and deflection of the beam for a given load.
