If the beam is to carry a total uniformly distributed load of 250 kN over its span of 5m,a) asses the suitability of the beam section .

Question

Produce detailed drawings of the beam

 

Answer 1

There is not enough information to fully answer the question.  We are given that

 

F = 250 kN

L = 5m

 

But if we knew a few more things, such as

 

(a) Maximum allowed deflection δ_max of the beam under load

(b) Young's modulus E of the material the beam is made of

(c) Cross-sectional area A of the beam

(d) Maximum allowable stress σ_max in the beam under load,

 

then we could calculate a few things to assess suitability.

 

Examples:

 

Is  FL/(AE) ≤ δ_max ?

 

Is F/A ≤ σ_max ?

Answer 2

Your statics textbook should have a formula for a distributed load of a beam in the appendix.
