Kerosene is placed inside a glass capillary tube having a radius of 0.5 mm. The kerosene inside the tube is measured to have a standing height of 59mm. Determine the true static height of the kerosene using a surface tension value of 0.035 N/m and Sg=0.8.

A 1.0 meter long A36 steel rod with a diameter of 40mm is lightly attached at both end of the rod, end A and end B. A collar is located in the center of the rod. The initial temp is 60 degrees C. The final temperature is 35 degrees C. Determine the force that must be applied to the collar so that the reaction at B is zero.Given:Delta T=25 degrees CE for A36 steel: 200 GPaCoeff of thermal expansion: 12(10^-6)/degree C
