(a) A water tank is completely filled with liquid water at 60°C. The tank material is such
that it can withstand tension caused by a volume expansion of 4%. Determine the
maximum temperature rise allowed without jeopardizing safety. Take water coefficient
of expansion (ß) as 5.22 x 104 1/K at this temperature.
(b) A weight, as shown in figure Qlb-(a) has to move at constant velocity of 2 m/s on an
inclined surface with a coefficient of friction of 0.27. The width of the block is 20 cm.
