Weights are now added in convenient increments, and at each increment the pressure<br />
gauge leading is observed. A similal set of resrilts is then taken with decreasing<br />
weights. To guard against the piston sticking in the cylinder, it is advisable to rotate<br />
the piston gently while the pressure gauge is being read.<br />
