• q = uniform load per length unit of beam (N/m, N/mm, lb/in). Equation 1 and 2a can be combined to express maximum stress in a beam with uniform load supported at both ends at distance L/2 as.
  • Does the balance change if one-fourth of the beam is cut off and placed on top of the shortened end of the beam with the edges together (Fig.)? If the balance does change then what force should be applied and at which end, to restore the balance?
  • Stresses: Beams in Bending 239 Now AC, the length of the differential line element in its undeformed state, is the same as the length BD, namely AC = BD = ∆x = ∆s while its length in the deformed state is A'C' = (ρ– y) ⋅∆φ where y is the vertical distance from the neutral axis. We have then using the fact that ρ∆φ = ∆s

  • Dec 26, 2020 · A uniform beam of length L is under a concentrated load with a constant value of ω0 in the middle of its opening (L/2) according to the figure. If the two ends of the beam are trapped and the differential equation governing its deformation (y) with the (initial) boundary conditions is given as follows, obtain its deformation at the point x =L ...
  • Apr 07, 2016 · Example - Beam with Uniform Load, Metric Units A beam with length 5000 mm carries a uniform load of 6 N/mm 2. The moment of inertia for the beam is 78125000 mm 4 and the modulus of elasticity for the steel used in the beam is 200000 N/mm 2. The height of the beam is 300 mm (the distance of the extreme point to the neutral axis is 150 mm).
  • The initial investigations have taken into consideration the uniform beam, having a length m and a rectangular cross section with the following geometry: width mm and thickness mm. The physical-mechanical properties are the volumetric mass density ρ = 7850 kg/m 3 , the longitudinal elasticity modulus N/m 2 , and the Poisson ratio μ = 0.3.
