A simply supported beam AB of span, L = 24 m is subjected

A simply supported beam AB of span, L = 24 m is subjected to two wheel loads acting at a distance, d = 5 m apart as shown in the figure below. Each wheel transmits is a load, P = 3 kN and may occupy any position along the beam. If the beam is an I-section having section modulus, S = 16.2 cm3, the maximum bending stress (in GPa) due to the wheel loads is_______________

	σ	=	m
	y		I

⇒ σ =	m	. y =	m
	I		z

=	28.5 × 10⁶
	16.2 × 10³

(m = 3 × 9.5 = 28.5)
= 1759.2 GPa
