1) Objectives of Water Supply System
2) per capita demand of water
3) variations in water demand

Torsional Vibrations. Undamped torsional vibrations (rotations back and forth) of a wheel
attached to an elastic thin rod or wire are governed by the equation I0θ
00 +Kθ = 0, where θ is
the angle measured from the state of equilibrium. Solve this equation for K/I0 = 13.69sec−2
,
initial angle 30◦
(= 0.5235rad) and initial angular velocity 20◦

Цhat is a method statement?

Laboratory tests on human teeth indicate that hte area effective during chewing is approximately 0.25 cm^2 and that the tooth length is about 1.1 cm. If the applied load in the vertical direction is 880 N and the measured shortening is 0.004 cm. Determine Young's Modulus

A steel cube is subjected to a hydrostatic pressure of 1.5 MPa. Because of this pressure the volume decreases to give a dilatation of -10^-5. The Young's Modulus of the material is 200 GPa. Determine Poisson's Ratio of the material and also the bulk modulus.
