Direction: A massless beam has a loading pattern as shown in the figure. The beam is of rectangular crosssection with a width of 30 mm and height of 100 mm.

The maximum magnitude of bending stress (in MPa) is given by

1. 60.0
2. 67.5
3. 200.0
4. 225.0

Correct Option: B

M_{X = 2.5} = 1500(2.5) −	3000(2.5 − 2)²
	2

M = 3375 Nm.

M	=	σ
I	=	y

σ =	33752 ×	0.1	= 67.5MPa
