At a point in a piece of material there is a tensile stress of 90 MN/m^2 upon the horizontal plane, and compressive stress of 45MN/m^2 upon the vertical plane. There is also a shear stress of 45MN/m^2 on each of these planes. Determine the planes of maximum shear stress and value of maximum shear stress at the point from the first principles.

A flow of water of 100 litres per second flows down in a rectangular flume of width 600 mm and having adjustable bottom slope. If chezy’s constant C is 56, find the bottom slope necessary for uniform flow of 300 mm. Also find the conveyance K of the flume.
Discharge, Q = 100 litres/second
= 100/1000 m^3/second …[We know that, 1 litre =1/1000 m^3] Width of the channel, b= 600 mm= 0.60 m
Depth of the channel, d = 300 mm= 030 m
So, Area of flow, A = b.d = 0.60 x 0.30 = 0.18 m^2
Chezy’s constant, C = 56
Find the slope of bed(i) = ?

What is the formula of conveyance K ?
We know that
Discharge (Q) = A.V
= A.C(m.i)^1/2 ……………………. From chezy’s formula
Which can be written as Q = K(i)^1/2
Where K = AC(m)^1/2 & K is called conveyance of the channel section.
Conveyance of the channel : –
Where, K = Conveyance of the channel section.
A = Area of the channel
C = Chezy’s constant
m = Hydraulic mean depth or radius
