Question

Calculate the modulus of rapture of a beam of breadth 0.2m and depth 0.5m given that the failure load under centre-point loading (CPL)of span 0.7m is 2000N

Answer 1

Modulus of rapture σ = 3Fl/2bd² where,

σ = modulus of rapture

F = Breaking load

l = length

b = breadth

d = depth.

σ \(=\frac{3\times2000\times0.7}{2\times0.2\times(0.5)^2}\)

σ = 4200/0.1

σ = 42000 N/m²
